Ok, this is the third time I have lost my progress! I updated to the latest patch get into the game and noticed it deleted my saves. I was at level 13 and after the patch it took me back to a save from level 8. Before the update I was having problems with the game saying it was "auto-saving" but it really wasn't same goes for the 'quick-save' function. At this time I don't even want to play any more because I'm afraid I am going to put in 3 hours worth of game play again only for it to get deleted or 'lost'.
Obsidian, are you aware of this problem?!
EDIT: Just read the Topic on this issue, will give some of the solutions a try.
