[1.2.0.5] Grava'Thul debuffs himself with Entropic Void in SR

Hello, devs and players!

Today I saw something strange happened to Grava. Here are the videos:

It seems that whenever Grava summons Entropic Voids via Aura of Agony, they debuff him instead of player most of the time (as you can see in first video, at 34 seconds mark I got same Entropic debuff), in second video I was not affected at all :grin:. Some Voids even despawn pretty fast - they should live for 12 seconds, again according to GT. Poor Chthonian creature…

Any ideas? What happened to him?
