Sadly I didn't backup. So I suppose I'm boned until the next patch that may or may not address this issue? Has anyone else had this problem?
Just to make sure I didn't miss-understand you...
Did you try to load a game that was started with the latest 1.2 patch?
If you weren't running any mods then you might send the dump to IC support email.
Or,.. did you start a game with 1.011 and try to load it in 1.2?
This won't work for anyone.
