Freelancer

I think its because that Freelancer mod manager moves the saves to its own folder, because the mods use different gameplay settings, bases, ships, weapons, systems, etc. I mean, imagin what would happen when you load a save that has you on Planet IMAROCKSTAR in the System ROCKANDROLL with the ship ELECTRICGUITAR, without any mods. oops. Cant find any of those?!? Error!!! and your save gets corrupted. That is why.

That would be why. Mods change things about the game, so it's almost like playing a different game. Stuff is different on some mods then others, so, like he said, say you have a mod that let's you fly a cloaking Valkyrie. Then you take the mod off and try to get on that ship again. The game won't know what your flying or what weapons your using, so your game will just crash.
