I just saw a Morning Light (or is it Morning Star? I mean the rare Light weapon that's not found in the Bazaar), which is supposed to be a weapon, become a creature instead. It was played from the level 1 AI's hand. After that, it hit my Skull Shield and became a Skeleton (which retained the 'invulnerable' status) - so, not that I'm complaining in this case since it was to my advantage, but it really looks like it's not supposed to happen. Don't know if that matters, but the AI's element was aether and mine was darkness.
