I was playing a GalCiv II game, all was going well. Then all of a sudden for no apparent reason, my logistics rating went from 24 (or 25, don't remember) to zero. I couldn't think of any in-game explanation for this.

Also, a lot of my custom ships completely disappeared as well from the shipyard screen. I didn't do anything to the game files or touch any of the settings that I think could bring this about. Has anyone experienced anything similar?

If you need to know more I'll reply as soon as possible, just wanted to list the general problem.
