Great game and already on my Steam wishlist!
One bug I noted with the Demo 0.8.2. I'll kill a werewolf or a werebear and it will randomly turn undead. You'll move away, turn around and the corpse you just created is back up on his feet . It won't attack, nor does a damage indicator pop up over it. The "Loot" prompt will come up when you get close enough but the zombie is empty.
