and how it doesnt seem to know what GetUsedItemLevel is for ( http://geck.gamesas.com/index.php?title=GetUsedItemLevel&action=edit&redlink=1 )
If getuseditemlevel is zero, I think it means the item is sitting on the ground.
I can see this because with the animation "LoosePickUpGroundObject", this being zero is a condition. There is no condition on its sister animation, "LoosePickUpTableObject".
