No, that's not it. Corpses auto open if you check it in injection/razor. The current no loot fix works in such a way that you can't open the corpse to loot. Injection can loot the corpse even if it doesn't open it, as long as it has "seen" the items, which it has during the duel. So if someone didn't forget to set the area, the things were looted with "emptycontainer"--->target corpse or specificly grabbing an item you know the ID of.

This has been fixed already, it's just that RunUO doesn't have that feature on distro:p
