Tried, save deleted.
As I said, I had a backup, and it deleted itself.
I played this game on another computer where I got the save and it deleted itself. Basicaly since all of those where the same save, just copys of eatchother, and they all deleted themselves at the same time.
So its not the game engine, it is the saves.
