Today, System Shock 2 crashed while playing co-op with two friends. It happened when going through a bulkhead in the Hydroponics area. The problem is, two of us have backup quicksaves from before we entered the previous bulkhead. and one of my friends accidentally quicksaved after going through it, so some weird stuff happen when we start the game (players standing completely still and things like that).What should we do to fix it?

The game has worked with no errors until now, we had a long session of System Shock 2 co-op yesterday that worked fine.
However, we all manually saved before ending the session yesterday, could these be loaded?
