Difference between revisions of "Deep Space Kraken"

Revision as of 07:59, 27 February 2018

The Deep Space Kraken was the name given by the community to a bug prior to version 0.17. The name Kraken comes from the legendary deep sea creature that supposedly attacked and sometimes destroyed ancient sailors' ships, a good analogy for "something" unexplainedly attacking and destroying players' ships. Since the original bug was fixed, "Kraken" has become a symbol for many bugs, which are often not related to the original bug.

The Deep Space Kraken was a famous bug and is namesake of other bugs in Kerbal Space Program. It was removed with version 0.17. The bug could be triggered by moving at high velocities in the game. The cause was that KSP prior to 0.17 would move the ship in space, instead of moving space around the ship. The high velocities caused floating point errors in the code which caused parts to be slightly misaligned or misplaced on the ship which would in turn cause the physics engine to detect the parts breaking off or colliding.

A fix was implemented in 0.17, involving offsetting velocity to the universe around the vessel meaning that the focused vessel will always be at a low speed. However, this caused a similar bug to appear, called the Deep Space Cthulhu, which can break apart ships when quickly switching out of high time accelerations (as of 0.17). Another side effect of this fix is that the Kraken can strike vessels which are passed closely and at very high speed, because the speed is offloaded to them instead of the active vessel.

Main Krakens

This is a list of bugs that are attributed to the Kraken bug but are actually the result of physics glitches.

General Kraken

The gyro kraken strikes a lone kerbal!

General Kraken or The Kraken mainly occurs during interplanetary travel. General Kraken only breaks a few parts of a spacecraft which may then collide and result in explosions. The Kraken may also force parts slowly through each other and result in catastrophic explosion. Unlike the Cthulhu, the Kraken tends to attack when exiting the Map View and IVA mode. This Kraken was largely fixed much earlier in the KSP development, with a system officially named "krakensbane" which changed the reference point from Kerbin to the current vessel, thus reducing the rounding errors that started the chain reaction.

Gyro Kraken

Gyro Kraken is when a spacecraft will spin around and vibrate so intensely that the spacecraft will be obliterated. The rate of spinning is so extreme that it is impossible to be replicated manually. This is actually a bug with parts clipping through each other and colliding with each other, causing what is also known as 'ghost forces'. On occasion, it will appear as though something is hitting your craft at high speeds rather than just spinning out of control.

Warp Kraken

Warp Kraken is a bug that attacks Kerbals exiting spacecraft that have just come out of a high time warp. Upon contact with the surface the bug causes the kerbal to be shot out of the solar system at an insane velocity (possibly exceeding the speed of light) while destroying all spacecraft in the vicinity.

Deep Space Cthulhu

Deep Space Cthulhu is a fan-made term for a version 0.17 bug similar to the Kraken, except it only seems to attack when exiting high time warp speeds. Instead of adding phantom forces, Deep Space Cthulhu instead tends to detach parts from one another. In milder, yet more infuriating forms, Deep Space Cthulhu will instead detach small groups of engines, making it impossible to perform orbital burns. Cthulhu is a cosmic entity from H.P. Lovecraft's novels, and bears a slight resemblance to a Kraken. It has been reported that Cthulhu can attack ships that are still on the launch pad when coming out of a high time warp.

Wormhole Kraken

The Wormhole Kraken has been reported to affect ships as they are leaving Kerbin's atmosphere. If there is a lot of weight below a decoupler (which is most likely also the center of mass), the rocket will clip through itself. While in Kerbin's low atmosphere, the bottom part of the link will start moving faster than the top due to the normal acceleration. Once the top of this broken part passes the actual top of the rocket, the entire rocket will obliterate itself, leaving no two pieces attached.

Hell Kraken

The Hell Kraken

Mun rover loaded again after being affected by the hell kraken (v. 0.22)

The Hell Kraken is a bug which was discovered during the 0.21 version. It seems to strike when a kerbonaut on EVA hits a celestial body's surface, causing the screen to turn black, with the UI remaining though. The altitude will remain at 2/3 Mm which displays as "666,666 m". As of version 0.23, the altitude GUI will display "666,666", and will change numbers rapidly like so: "666,666"-"555,555"-"444,444", etc. A good example of this is Danny2462's famous "Having Fun in the Solar System" video.

The navball also disappears, and when returning to the space center, the screen remains black and the game must be manually closed from the desktop. This kraken is particularly dangerous because when encountered on the surface of a planet, it causes all craft in the vicinity to be destroyed, and those left are shot out of Kerbol orbit. The log in Debug Toolbar shows "look viewing vector is zero". As of V1.1, the altitude GUI will go blank, and the game will crash.

NaN Kraken

The NaN Kraken is a bug which can only be evoked if the orbits of celestial bodies are altered, via a mod or the alteration of the game's code. If a ship is on the surface of a planet, and another planet is suddenly moved so that the craft is within its SoI, the sudden change in gravity will cause the craft to go towards the latter at incredible speeds, and will sometimes even go through a planet to accomplish this. Please note that the gravity of the second planet does not have to be greater as only one gravity source is allowed at any given time.

Kore Kraken

This bug was [1] discovered in KSP version 0.22. This type of Kraken will only occur when parts somehow manage to come to rest below the surface of the sea of Kerbin. When resumed some parts may not make contact with the ground and can actually float through the ground and towards the core of the planet. When the parts get near enough to the core of the planet, they will gain extreme speeds (about 97.8% of the speed of light) and shoot out towards infinity, not actually hitting the far side of Kerbin (likely because tick-based physics at high speeds can easily "miss" collisions) when they shoot out.

6 Death Kraken

The 6 Death Kraken attacks mostly during early launch stages. It strikes craft that are inside of Kerbin's atmosphere. Around 6,000 meters, at random, the craft will accelerate suddenly, blasting out of view. The trajectory will wobble extremely fast. The engine sound will become warped and robotic-sounding. It is impossible to recover from this form of the Kraken, as the craft is out of view and extremely likely to crash. You can save your Kerbal by going on EVA out of the ship and hope you survive. Reverting back to "Launch" or "VAB/SPH" may not fix it, as this Kraken will most likely strike again. The only way to vanquish this kraken is to re-install the game. The 6 Death Kraken has not been confirmed in .24 or .25. It appears to be caused by the game attempting an extremely high physics warp, which breaks everything.

The 6 Death Kraken has been sighted and confirmed for 1.0.5, as of 12/15/2015.

A similar, less dangerous, kraken has also been sighted, where physics will accelerate slightly at 6,000 meters, similar to physical warp but less intense. No actual acceleration is observed, but it is similarly relentless.

Ass Kraken

The Ass Kraken - the worst of them all

The Ass Kraken, discovered by forum user Clockwork13, is a rare kraken that occurs while loading quicksaves. It makes the screen get completely wiped out by those red fire particles that can be seen when entering atmospheres. The screen then turns white, and the game needs to be manually closed. Once the game is restarted, all of ships will disappear except for EVAs and Flags. Occasionally debris in orbit around the sun will survive. When reopening the save, it says that the parts to just about all of ships are missing. This doesn't just affect ships but also affects the research. All archives go unharmed, but random parts go missing. The node is still researched, just a lot of parts require another entry fee to gain access to them again. There seem to be varying degrees of Ass Kraken, sometimes deleting parts and ships, and other times leaving them unharmed. This is probably the most devastating, but rarest Kraken. The Ass Kraken has been confirmed in .90, so be careful with quickloading. The name stems from the discoverer's initial frustration after discovering the Ass Kraken. It is unknown if this bug occurs with recent versions of KSP.

Map Kraken

The Map Kraken - You screwed something up.

Appears in 0.24 only in the map screen when switching directly to it the moment you get on the launch pad. The vessel will be destroyed and blasted through your map screen as you stand by, helpless to say a word. This is an 'Ultra-rare' Kraken and has not been able to be reproduced. (This may be due to the fact that the incident shown to the right occurred in the presence of mods.) This Kraken has been able to be reproduced by Forum user Resident_Crash_Lander without the presence of mods; However the criteria for this occurring are incredibly rare, as you need a launch clamp to detach from the launchpad and collide with a vessel in motion and open the map at the exact time of the collision, This occurred in .24.

Minor/Poorly Documented Krakens

Apocalypse Kraken

The Apocalypse Kraken is a bug of unknown cause and unknown rarity. Little is known about this bug, because it has been recorded only once. This report has not been confirmed. It causes the craft to accelerate to ridiculous speeds, exiting the solar system in seconds. After leaving the solar system, the map shows empty space. Reverting the flight will return the craft to kerbin, but the map will remain empty. No sun or Mun will appear in the sky, and kerbin experiences an eternal night. This affects all save files, lasting until the game is reinstalled.

Kerbin Kraken

The Kerbin Kraken is a bug found in 0.25 to 1.0 or earlier than 0.25. It is a fairly small glitch that attacks when you are time warping toward Kerbin and you enter the map screen. When the ship crashes into Kerbin with the map screen open, Kerbin will explode and you will be on an escape velocity out of the solar system.

Ghost Kraken

The Ghost Kraken is a bug when entering time warp. The ship being controlled will bend until most of the parts have detached. Phantom forces will pull parts down to the planet until they crash into it. It is possible that when you reselect the ship's command pod the ship will duplicate itself and will be okay. It is impossible to time warp while being affected by this kraken because the parts are under acceleration.

Kerbal Kraken

This Kraken occurs in 0.24 & 0.24.2 when the player attempts to edit save file configuration settings of the original three astronauts--or possibly all active astronauts--at any time, whether the game is running or not. If a player attempts to edit something in the .Persistent file in the save folder, the game will glitch, causing the player to be unable to access the VAB and SPH. The player can access Mission Control, R & D, The Tracking Station, and the Astronaut Complex; However, when attempting to return to the KSC screen, the screen becomes locked and stuck. The player can still click buttons and control some parts of the game, but cannot exit the current building or the save file. The only fix is to delete the affected save file. This Kraken is particularly dangerous because it requires you to delete the entire save file.

In .90, a version of this Kraken can appear when you fire a Kerbal (even one who is MIA) if that Kerbal had completed an achievement (such as first flight, first Mun landing, altitude records, etc.). Editing the save file to add the Kerbal back in with the "Dead" status will allow the game to work normally while still freeing up the slot to hire another kerbonaut. There is a fix among the Stock Bug Fix Modules that will prevent this bug from happening, but any save already hit by this will still need to be manually edited.

Space Center Kraken

This Kraken occurs rarely when you build a vehicle that extends beyond the VAB or SPH limits, upon leaving either It causes you to zoom in near the VAB, and freezes your camera control. It is difficult but not impossible to access the main menu from this state but the game must be restarted in order to access the save file in which it occurred again without this kraken appearing. This has only been observed in versions .24, and .24.2, and was reported by wiki user TJ McCaustland.

Launchpad Kraken

This Kraken occurs any time an exceptionally large spacecraft is placed on the launchpad in version 0.25. Once the craft has loaded, the weight of the spacecraft triggers the explosion sequence of the launchpad, destroying first the launchpad, and then breaking the craft apart and sending any surviving pieces flying in different directions. The remaining pieces can then destroy other facilities. This can be avoided by using Launch Stability Enhancers to elevate the heavy craft above the launchpad. This may not be an actual Kraken, rather a bug associated with version 0.25. Still, it's something to worry about.

Quicksave Kraken

A new, quite poorly documented kraken can cause quicksaves to exhibit what is known as "loading teleportation", i.e. when we quicksave close to a ground comms structure, like the one on HarvesteR Massif, the loaded quicksave will contain missplaced vessels and flags, that will levitate in the air indefenately...

Solar Kraken

This Kraken happens very rarely when switching to a ship in a 180 degree inclination in an orbit. Then, it destroys the entire solar system, removes the orbit indicators, and leaves only your ship, and some random parts flying near you, even if you haven't unlocked them with science left. Reloading the game fixes this.

Phase Kraken

Phase Kraken is when parts of spacecraft will clip inwards through itself when anchored weakly and enough thrust is applied. This phasing happens not vertically, but rotating inwards around an anchor point. Usually happens with boosters, the parts will phase through the craft at time warp and eventually explode, either because you leave time warp or the thrust stops being applied at it whips back and the other ends collide, destroying all parts in the explosion radius. Note: this may fall under another Kraken or not actually be a Kraken, but I consider it to be a Kraken, and its own one. Known to exist in 1.0.4.

Rover Kraken

A possible new kraken, it occurs frequently when testing rovers on Kerbin. Rovers will hit invisible bumps, coming a few meters off of the ground and will usually land wheels up. Any rover with combustible parts is usually destroyed on impact. It appears to be very common in 1.0.4. The bug is probably caused by spaces in between Kerbin's Terrain Tiles, that act as bumps and cause R.U.D - Random Unplanned Disassembly.

NoMass Kraken

A very interesting Kraken manifests itself when a craft's mass leaves the positives. This can happen by part-editing, for example let's say we create a part with -20.0 mass value. This object, if launched alone, will float up to around 0.7 meters, then remain stationary and immovable. It can still be destroyed. Now, if an object is attached to our massless part, a spaceplane, for example, we will observe it get unmovable. Upon applying thrust, the affected ship will start shaking rapidly, losing integrity and falling apart. Objects free of the massless piece will behave as expected. This bug was first checked by Alto and has not been proven. It is anticipated that the momentim equation returns a damaged value, that cannot be acted upon by other parts.

Docking Kraken

The Docking Kraken does not actually affect the craft itself, but rather interferes with its instruments, showing a sudden and inexplicable gain of velocity, even if the actual relative velocity is zero. While not damaging, it makes docking nearly impossible, unless the affected player is very good at flying by eye.

Water Kraken

This Kraken may happen when you are landed on water, and you time-warp resulting in your kerbal dropping 1000 meters into the water. It is caused by the physics engine not rendering the surface correctly and allowing the kerbal to fall, can cause minor spaghettification.

Intercontinental Kraken

The Intercontinental Kraken was arguably, the first ever Kraken. It happens in 0.7.3 (the pre-alpha stage) when you move too far from the KSC. Your craft starts wobbling and possibly completely disassembles it self. (R.U.D)

Launchclamp Kraken

The launchclamp has extreme integrity... Because of that it can survive a Kraken. Let us have some fun and trigger one! Place a big rocket on the launchpad with one clamp so it bends. Then engage some engines so that the clamp is strained more! Next step... hit the craft on time warp with a different craft and object thrower! Bam! The clamps seperate upon touching the runway/launchpad with their top and damage it! Luckily they reenter the atmosphere after a nice hop! Mine ended up on the arctic as well as in water... Have fun! Please also write Your experience to make this important Kraken data more valid!

Spaghetti Kraken

Sometimes, after a Kerbal disembarks from a spacecraft on a slope, the Kerbal begins falling strangely, with its limbs stretching to painful and insane lengths, similar to the effect caused by black holes' "spaghettification". The Kerbal keeps "falling" even after it hits smooth terrain and eventually gets killed from the "impact". This Kraken is found in Version 1.2.1. Reported by wiki user RedRapter a.k.a forumer RandomGuy1824

Drag Kraken

The Drag Kraken is a combination of krakens that appear when you edit the drag value to a super-high value, such as 123456789.0. One of them is the Superpowered Kraken, which makes the planets overlap each other and destroys the orbits. It even gltiches the sun! Another outcome is that your spacecraft explodes and you start moving left And up if you look down and the camera is on the right side of the Runway, or the Launchpad. That's what happens with the stock VTOL. With the stock VTOL, the spacecraft completely glitches and shoots the capsule off at a speed that’s hundreds of times faster than light. This may be caused by some kind of variable error. After that, the capsule starts shaking and glitching very hard. Going EVA at this point will launch the kerbal at over a hundred quintillion meters per second. After you try to return to the solar system after a little timewarping, the Superpowered Kraken takes over and wreaks havoc on the map. Also, when reverting to launch at a point, the terrain is completely annihilated, and in a split second, the final Hell Kraken effect is triggered.^[1] One can edit the drag values to the negatives... Alto, again... Not tested much but I found some nice lift bugs and lift surface movements that reminded me of dancing... Also parachutes go insane!

Superpowered Kraken

This Kraken was very severe (And funny) when it still existed. It was activated by spinning extremely fast, and doing an EVA after the craft's spinning was slowed by something unknown. The effects were that you would go faster than light, causing the game to bug out and glitch map view. If you went to focus on the smallest moon, Gilly, it would have EVERY other celestial body overlapping it. The Kerbolar System would lose all meaning, as orbit lines shake around, planets blink, and the KS also shakes around. Sometimes it looks like it was duplicated and is blinking rapidly. This also affected every save file, and you would need to restart KSP to fix it. This is probably caused by KSP having a supermassive number, which then makes KSP completely trash numerical accuracy. This was fixed in 1.2 when the new PhysX rolled in, fixing the glitchiest kraken in KSP history (As of 1.2.2). Not to get mixed up with the Gyro Kraken.^[2][3] (These videos show this kraken in action)

Wheel Kraken

The Wheel Kraken is a Kraken which is activated by wheels. The Wheel Kraken can make parts with wheels in them float up in the air, and go out of control. This Kraken is also the culprit of the thing where if Kerbals are hit with wheels, the hit Kerbal stretches before hitting the ground and exploding. The stretched Kerbal can damage spacecrafts and also damage the KSC. The outcome is the Spaghetti Kraken's main effect. This is confirmed for KSP 1.1.2.^[4][5]

Lock-Kerbal Kraken

This Kraken is very rare, and if your Kerbal ragdolls after something is triggered, and get up, you will be locked in the position that you were in when ragdolled.^[6]

Compact Kraken

The Compact Kraken is an occurrence when having a large craft go through maximum time warp, and out very quickly, The craft will squeeze together making a glitchy ball or other shape of parts, and immediately explode.

Thermal Cooling System Kraken

This Kraken can be rarely found when after docking a part with Thermal Cooling Systems (doesn't matter how big or small the docking part is) onto a surface base and then exiting the game or going to the Space Center, such part will start spinning and alternating from left to right. This Kraken can destroy entire bases by flipping them completely. A "solution" to this problem is to quickly undock the part, though it will still spin out of control until the Thermal Cooling Systems are destroyed, which is unpractical as because it may also spin towards a base.

SAS Kraken

This is a kraken that seems to attack in 1.1 and beyond if SAS is left on during flight while a ship is orbiting a celestial body. The SAS Kraken can rip apart a ship and kill the entire crew very easily. It is currently not yet known if this is actually a kraken or not, but it can do nasty damage to an unsuspecting player by destroying a craft.

Impact Kraken

This Kraken, found in the 1.1.x versions, toys with debris resulting from collisions. Usually it manifests when something hits a celestial body at high speed, but sometimes it can be caused by internal self-collision (most notably, by using clipping parts). It propels debris away with impossible velocities, sending it to escape trajectories from Kerbol. This video demonstrates the summoning of the Impact Kraken through clipped parts (the effect itself is at 1:35).

Skycrane Kraken

This Kraken, found in 1.2, affects the stock vehicle rover+skycrane. A slightly modified skycrane, if decoupled while the rover is stationary, appears to hit one wheel. It then sends the rover flying, spinning wildly. This Kraken is reproduceable with these modifications: remove the solar panels, add Gigantor XL panels on the sides of the command module, add a PB-Nuk generator on top of the command module, and use struts to connect it to the command module. Next, replace the wheels with 4 Rovemax M1 wheels. This Kraken can be alleviated by throttling the skycrane up slightly before releasing it. These modifications included adding an XL parachute to the top of the skycrane.

Launchpad Kraken

This Kraken, reported by steam user Cpt.Bob, is achieved by simultaneously launching your craft and reverting to launch. This causes the craft to have random parts laying sideways on the launchpad, have all engines running, and have no affect by physics. Once the craft is launched, physics start affecting the craft, and it goes to hell, as the craft is likely unbalanced by the Kraken. This Kraken is only reported in 1.1.2

Vehicle Return Kraken

This Kraken has apparently an unknown cause, but has been observed multiple random times. When a Kerbal is returning to a craft from Eva, the camera switches to the vehicle. The Kerbal stays on the ladder, and is not inside the vehicle. You are unable to switch to the Kerbal, making it seem they had a heart attack. This Kraken is reported only in 1.1.2 and has only been observed to affect the PPD 12 Cupola Module and the Mk2 Lander Can.

Editor Kraken

This Kraken can be found by quicksaving and editing a kerbal. The craft (And Kerbin) is destroyed, with only the cockpit remaining (Currently only Mk-2 Inline Cockpit). You cannot battle this Kraken through conventional means (NOT EVEN THE SUN CAN HELP YOU). You have to DESTROY the craft using HyperEdit, which is barely enough to rid of the Kraken. This has only been tested once (Currently), and there are no recordings of this Kraken in action, only one instance of this has been seen. This Kraken is a nasty one, especially when you need to change a little thing, such as a kerbal's data. This can also be called the Karma Kraken (Well, kinda), since you are bending KSP to your wants. This has not been reproduced, and the finder of the Kraken is scared to try it again. This has been reported in KSP 1.2.2. This might be fake.

Relativistic Kraken

The Relativistic Kraken emerges when a craft accelerates to a very high speed, like near lightspeed (either legitimately, i.e. through KSP-Interstellar fusion drives, or as a result of another type of kraken). It begins oscillating the craft along all axes, making it impossible to turn if the SAS or RCS aren't very powerful. This can easily result in missing the retrograde burn and flying by your target at insane speed (if the acceleration was deliberate).

Targeting Kraken

The Targeting Kraken is found when you target an external craft while on the launchpad with a clamp attached to your rocket. If you enable SAS and set it to target, the craft destroys itself, launching parts at near light-speed. The cause may be that the craft is trying to move toward the target, but it can't, so the game tries to force it to face the craft, but the launch clamp prevents it from moving, so it keeps trying to force itself to face it building up a tremendous amount of speed.

Changes

0.17

• (Bug fix) 'Off loading' velocity to the universe alleviated this problem, though it still exists in 'new' form.
