Mobs not following attacker?

[aridale]

I ran about 10 different searches on this and didnt find any answers.

What Im wondering is why dont mobs follow you once you attack em? Is it grid related? (I know nothing of grids havent messed with em yet) Im not tryin to get mobs walkin around by themselves Im talkin about when you attack somethin it just stands there. You can back up where it cant hit you and it wont move itll just stand there like its perma rooted.

Like I said I ran 10 different searches tryin to find out if it was just somethin I was missin but I couldnt find anything ever remotely similar. One guy said his mobs didnt move when he attacked em but no one ever responded to his post so there was no help there.
