mage pets in lower guk pull the whole zone
 

Mage pets in lower guk appear to have some kind of pathing or clipping issue. On three different occasions the pet fell through the world and pulled the zone.

Once we were just entering. I had my pet and we fought some mobs near the entrance. The It fell through the zone and suddenly a massive zerg rush came.

Another time we had traveled a bit in, I had my pet with me. Suddenly, it was not with me, and then the whole zone appeared.

Finally, we made it to safe hall. I summoned the pet there. The whole zone appeared shortly thereafter.

I don't know exactly the issue, but it appears to me that the pet is clipping out of the zone and then clipping in somewhere else, where it pulls everything.

This happened when we were playing on November 20th on the Red server

I've had this happen on my shadowknight as well, while I was camping executioner. I assumed it was simply warping to a different floor, aggroing something, then warping back to me but who knows. The pathing in Guk can be pretty awful.
