The Problem:
Attacking mobs in Shattered Halls instance causes the server to disconnect. At first I thought it was just me, but I tried to do the instance 4x now, at different times of the day, and it always disconnect me, and other players, from the server.
Entering the instance doesn't cause the disconnect, but attacking an enemy inside will.
It may be worth looking into.
How it should work:
The server shouldn't disconnect and you should be able to complete the instance naturally, even with bots.
How to reproduce:
Pull a mob/any enemy in Shattered Halls with 4x playerbots in the party.
Character the bug occurred on:
Yorktown - the main toon I was controlling.
I also have 4 playerbots in my party.
