Version 3.0 for Kerbal Space Program 1.11.0

Released on 2021-01-03


WorldStabilizer no longer works as of 1.11, it no longer protects against the 1km spawn bug (and its presence in 1.11 seems to cause the bug to evolve into a vicious kraken) so take special care when spawning crafts containing at least these parts, or don't use them anymore:

  • J Deployment Bay
  • J Inline Large Docking Port
  • Avatar Cargo Ramp
  • Humpback Cargo Ramp
  • Stail Cargo Bay (Mk1, not Mk2)

  • Added Localization support.
  • Added missing SAS module to all drone cores.

  • Fixed K and KH cargo bays and hollow fuselages appearing in Fuel Tank category (moved to Payload).
  • Fixed missing bulkheadprofile in RCS ports.

  • Moved the following in from OPT Legacy:
    • 2.5m Nebula Shock Intake.
    • VTOL Wrapper engines.
    • Avatar tilt and WarpJet MARGE engine.
    • DepthMask assets.
