Enemies don't follow pathnodes...

[Lewk]

Ok, it seems I have hit another problem. The enemy follows the nodes as they should, with their triggers disabled. So, I turned triggers on, the monster chased me, but once I came to a corner, the monster was just trying to get to me in a straight line. Obviously, he stopped following the nodes after he noticed me.

What I need to know is how to get him to follow a a certain node, if something blocks his path.
