NPC Spawn Issue: Corpse too far away.

[Kirdan]

Corpse too far away.
You may not loot this corpse at this time.

I've been getting these messages intermittently while standing directly on top of corpses trying to loot them today. I've tried using /loot and relogging without success, once a corpse reports this message I can't find a way to loot it. So far it's happened to a werewolf in Kithicor, Ivie Bramblefoot in LFay, and a brownie outcast in LFay.

It differs from the message when I'm actually too far to loot them:

You are too far away to loot that corpse.
