I don't think this is a bug, but I thought I would be scolded for posting it anywhere else, since it could be a bug.
I procured a second ship and it is an escort. My primary ship is a science vessel, but each ship has a different set of crew assignments. It would be nice if the crew assignments were saved for each ship but each time I change from the science ship to the escort, I have one empty seat and have to assign a BO to it.
I know it is not that important, but would be nice to "fix" if the developers get time to fix it.
