Z axis aggro of spawns in Upper Guk
 

I was fighting some Ton Knights near the large croc pool in the back of the zone this morning in Upper Guk. I was in the little tunnels off to the side of that area. I've had this happen two times now where a vis shaman and other spawns from either above or below seem to path through those tunnels and aggro on me while I'm fighting the Ton knights who spawn statically and wander there. I had 5 frogs turn up while I was fighting 2 Ton Knights that I pulled into the little hallway.

I suspect that there is still some pathing going through the floor/ceiling or something in this area.

This is happening in lower guk too. Was at the exe camp and mobs were taking shortcuts running thru corners and falling thru the world. They'd eventually path back to exe camp again, usually bringing friends. I even got AM once from exe (epic pull)
