I did an isolated test to check. Going through the code, I *think* it has to do with using the same bayID reference in MKS and USI_LS, as well as the right click menu not properly updating in the VAB. As soon as I go to flight, it goes away. The right click menu also doesn't update for the resource converters. I chased it for a little bit, but I didn't get very far with it and decided it was harmless enough to stop losing sanity over.
