Last night my guild downed Durumu. However, there was a lot of frustration with our pets randomly despawning and having to be called back out. This happened with my hunter, Skylerwolf - Illidan, our Mage and our Dk ghoul. Our lock was not there last night so unknown if would happen to them. But at random times in the fight our pets just vanished. They did not die as we did not have to Rez. We were not out of range as it occurred 20 seconds in when lusting as we were all close to boss and it also happened during the running around purple haze phase. Curious if others have had this occurr and or if Blizz aware.
