The Hidden Forest

There is a mob in ToV east that when you try to pull it back to the main room that you drop down into for ToV east instead of following you into the main room it will instead path off god knows where and aggro the mini wyverns that are before ikitair the venom and path back through the ToV north doorway and back to east. If you obviously don't clear to the north doorway you have quite the train on your hands.

I have been able to reproduce this basically every time I have entered ToV east. The specific mob that does this is the spawn which if you go in the left door (if you are facing dozekar) then the first door on the left.... there are 2 mobs in that door basically. One of those mobs when aggro'd will follow you to the main room however the other mob will loop through NToV.
