Disciple of Varashta Causing DEADLOCK crashes for party members in multiplayer

Is anyone else having crashes playing in multiplayer with the Disciple of Varashta? Everyone in my guild is getting deadlock crashes after 5-10min playing with one of our guys playing DoV. Tried everything I can think of to fix it with no luck. If we play without him no crashes we can play for 5+ hours with no hiccup once he joins non stop deadlocks for everyone.
