If you do not move the item before saving, the stats are not set. I did the same thing with the ring the soldier you heal in Aleroth gives you when you get to Verdistis. I saved a fairly nice ring after a couple of quick loads, and after another few tries, figured I wasn't going to get anything better, so loaded the previous save to find it was now a crappy ring. This ticked me off <img src="/ubbthreads/images/graemlins/memad.gif" alt="" /> and I re-loaded the better part of an hour to get something as good.
