@RoverDude There is a bug in 1.6.0 & 1.6.1 that can lock up the parts menu in the VAB if a bulkheadProfiles isn't defined for each part. The following thread discusses it. The following parts in this mod are missing a bulkheadProfiles definition: ./UmbraSpaceIndustries/LifeSupport/Parts/Greenhouse_Cupola.cfg ./UmbraSpaceIndustries/LifeSupport/Parts/Greenhouse_Inline.cfg ./UmbraSpaceIndustries/LifeSupport/Parts/LgRecycler.cfg ./UmbraSpaceIndustries/LifeSupport/Parts/MiniPak_0
