  • Fix the editor cargo UI not scrolling when the mouse positionis in between slots.,
  • Fix attaching parts in EVA construction mode within the range of a robot arm scanner.
  • Fix AttachNodes not displaying when the root part of a vessel is outside the construction range, but the part is and shoudl be valid as an attachment.
  • Fix partdatabase.cfg handling when running KSP from an alternate folder/location.
  • Fix issues with parts that have trigger colliders when rotating/moving them in EVA construction mode.
  • Fix deadline to include CB multiplier on vessel repair and construction contracts.
  • Fix placed flags falling down.
  • Fix extended tooltip not being updated on variant change for cargo part mass.
  • Fix exploit that allowed to produce infinitely many stackable cargo parts using the stack logic.

  • Fix EVA kerbals on ladders generating phantom forces.
  • Fix CoL marker positioning in EVA Construction/Flight Scene.
  • Fix EVA construction losing detached parts and invalid highlighting when exiting EVA Construction with a detached part on the mouse.
  • Fix Repair contracts not completing if they use the same craft as a previous contract of the same type in the same save game.
  • Fixed an issue that locked up the game when kerbal tourists were passed out in command seats and the game was saved after landing.
  • Fix satellite construction stock craft being created as debris, they will now be probes.
  • Fix errors when using the rotate and move tool in EVA construction mode on wheels and landing legs.
  • Fix EVA kerbals unable to use static ladders (Ladders on Launchpads and buildings, etc).
  • Fix crew transfers out of a part does not update its PAW.
  • Fix parts with variants in construction mode reverting back to the base variant when attached.
  • Fix issue that occurs with Plant Flag being active during construction mode.
  • Fix trajectory changes during rotation caused by MinRBMass being too high
  • Fix error caused by symmetrical parts in KAL action set if parts get decoupled individually.
  • Fix Jetpack andf EVACylinder refill only working with EVA Propellant.
  • Fix Smoke FX on twin boar engine.
  • Fix bug that caused individually dropped parts to slide on the ground.
  • Fix Actions from Symmetry counterparts showing multiple times in the ActionGroup Editor.

  • Fix discarding merged craft throwing an NRE in Editors.
  • Fix dropped parts being teleported to the ground when dropped in the air above the ground.
  • Fix NRE when placing a part buried in the ground in EVA construction mode.
  • Fix Placing wheels past the collider for the ground (half buried) will cause the craft to bounce uncontrollably during EVA construction mode.
  • Fix Construction Mode Parts dropping causing immediately large physics effects on vessels.
  • Fix parts during Eva Construction mode beingpicked up, dropped, or attached when a UI element is blocking the pointer. This was resulting in unwanted click-through.
