I have same problem , my void acting like imp (firebolt enemy) have Blood pact and Paranoia auras, Imp lost all abilities same as felhunter.. I reported few times but its already 3rd week i can't normaly play. Also i spend gold to buy books from Pet trainer but void can't learn anymore and rest of demons as well .. Just a money waisting.. Some of warlocks dont have any issues.. But seems Kronos team don't care at all. Sad...
