I'm working on my Full Action RPG Preview Map, and there are a couple of parts when heroes enter a rect and monsters are created all around them and ordered to attack the party. That works, but after some time they retreat to their creation point. Why is that? How can I fix that? I didn't even hurt them that badly and they just f*cked off!! (I could go after them if they weren't amphibious... but thats not the point I don't want my players running after coward creeps!)
