That one I'm used to, like when I've got someone to almost dead and they start screaming "mercy," or "I can't defeat you," but this has been mobs just straight up running away from the bosses/other mobs, toward the exit. Oh, and I didn't actually kill the hunter... I just raised my flaming hands and poof - he was gone before I could even start casting. But seriously, one random bug like that out of almost 200 hours played... not enough of an issue to bitch about, especially since he wasn't a quest mob, he was just some random guy that I was going to punish for poaching murder for the fun of it.
