Yes, it is sad that the newer iterations have caused problems with older great stuff. I am only a novice at this 3d modeling stuff but I will see if I can get that rather nice Star Trek looking Door/Airlock to work properly.
Today I updated my H.A.D.D mod to 1.1.0 and flew a rocket with a space station that has my new docking sleeve as it's core up into orbit to test the collar and sleeve system all worked fine. Only slight unplanned disassembly on landing. Probably should have added parachutes.
