Well, for PC users anyway. The bug in Thief: Deadly Shadows that caused saved games started on Expert difficulty to revert to Normal upon loading has been patched out.
Still no word on a means of recourse for owners of the Xbox version though, which suffers from the same bug. Since Thief is a single player game, it was not made for Xbox Live and therefore doesn’t have any easy means of patching. So you Xbox people, you’ll still be able to do stuff like shown above and still pretend you’re playing on Expert for a while longer.
