Currently playing a Sidar game, Noble difficulty, patch 'r'.
Not sure if this has been reported before, but temporary units duplicated by the Balseraph Hall of Mirrors seem to drop permanent items. I had this happen with my hero unit Rathus Denmora. The Balseraphs created a dupe, which I killed, and managed to pick up another +80% vs hero sword, which I gave to Valin. I was almost tempted to pull back everyone except Rathus to get more copies of his sword, but it seemed a bit like cheating...
