Pathing The Hole pathing bug

[Handull]

Just tried to fight a mob in the more or less safe hallway in the basement of the undead tower (the hallway that runs east/west with a door on one end and a staircase on the other with a door at the top of the stairs). After the mob entered the door off the west courtyard he didn't follow down the stairs but went into the wall and my pet unfortunately followed him. I tried to pull back my pet, but when I realized it was no use I loaded up my wc cap and waited for the pet to die so I could be summoned and see where the mob was, and maybe try to charm something else if I was really lucky. I was summoned to the hill opposite the undead tower courtyards and had a big train of undead running for me (so I hit the wc cap).

Seems to be pretty easy to agro mobs down around that tower and get them to path underground, causing them to sometimes build a train and then pop out on that big hill (from this time and other groups down there). Thanks
