mob runnng and landing god knows where
 

I have an issue with a mob fleeing and landing who knows where.

I chase a skeleton in qeynos2 and he pops out (still selected). Using #listnpcs I see he is at -999493, -999493, -999493).

I can summon him back, but it happens every time. I'm tried running azone to create new map files, this yielded no change in behavior.

Ideas?
