I figure this would go here, even though it isn't really a bug.
In the eastern alleyways of Lower, where the "Lower Loons" are currently holding turf, there's a placeable of the bugbear Trag Shark Slayer's corpse. Problem is, there's two of them. My guess on the matter is that two separate DMs thought to put it in and it ended up this way.
My suggestion is to keep the "Trag's Impaled Corpse" placeable, seeing as it's better positioned and the other one's description is faulty.
