I've checked my save game folder and everything is still there... But whenever I try to load one of my save games, the game crashes back to my desktop. There were also plenty of bug reports written by the game, one for each attempt of loading a save. So if you're interested in them, just tell me were to send them. I've also used your analysis tool and can provide the report file in case this helps.
Just as a note: everything worked fine before the latest patch - I was able to save and load and then I went to get some food. When I came back and started the game again it was patched and loading was no longer possible.
I would be happy if there's a solution besides starting a new game. I mean it's really a great game but sooner or later it's kind of boring doing the same over and over again.
