I checked the quest script to be sure, and it's supposed to spawn him at the exact position of the previous mob. So the best thing to do is just try to be sure the mobs die on nice, flat surfaces (which is pretty hard to do in CoM of course).
Also, no one is manning the forum 24/7 to do immediate things like on-demand server resets. I try to check in once a day though. However, if a zone is empty for appx 30 minutes, it will reset.
