Small bug that I have noticed throughout my playtime (all playtime was multiplayer).
Occasionally when you loot a chest or corpse (and once when I killed skeleton king), the loot will drop a few paces away, instead of where the chest/corpse/king was killed.
Hey SpinDrJr, could you please post a screenshot of what this looked like for you? What is probably happening is that the loot wants to drop where you are standing, but has to move because a player is in that location.
Curuin, the bookshelf loot is a different issue and is known.
