Just finished a big giant space station in orbit. Put a bunch of guys in an OKS hab module in one of the earlier launches. They didn't show up anywhere, except in the ground based kerbal management ui (hire/fire thing). Got the station finished. I installed crew manifest to try to access the kerbals in the module. It allowed me to move them around the station. Saved, quit, and now I can no longer control that space station. Log shows: [EXC 08:34:46.428] ArgumentOutOfRangeException: Argument is out of range.

TLDR: 1. Put kerbals in OKS hab module on VAB. 2. Launch OKS hab to space station. 3. Use crew manifest to move kerbals to other parts. This assumes I didn't put them into a bad module, which is also a possibility. Few questions: 1. Is there any way to remove those kerbals and salvage this savegame? 2. Barring that, Is there any way to save just the ship, and start a new game with that ship in orbit?
