I'm playing a rather unusual game which involved letting others build their ships, then sending me the database for play. One of the player's ships appear to be incorrectly classified as military when they should be civilian. They're reporting overcrowding for no reason, and then suffering maintenance failures. The ships show as civilian in the F5 window, and editing doesn't seem to fix it. The problem appears to be limited to ship classes that he designed, even if I've SM edited them some. I've had to refit a few (the players are all novices, and we're seeing how they square off), and the modified classes/ships don't seem to have the problem. The problem did occur in ships built to his class designs after play started.
The other players haven't had this problem. The only cause I can think of is that he said he was using the portable version.
