That's no good... Had you attempted any editing of those text-based files? The game does have a nasty habit of trashing Saves seemingly arbitrarily at times, even without any user input... Some of the files do keep track of the byte size of the files, and some have certain formatting and hold only certain data, and might have IDs pointing at certain other files - all of the info being interrelated. One mixed-up bit of data, and a Save can be ruined. Also, changing certain mods' status while not in port can trash the Saves, from the game not being compatible with the Save anymore. Hopefully, you don't have to go too far back in the Saves to continue your career...
