[Trial of the Naaru: Tenacity] /TK atuunement

[Zantrol]

Hello today i did the " [Trial of the Naaru: Tenacity]" quest and after we killed the last boss in HC arca Millhouse was still alive however was not able to talk with him and notthind happend at all. I take it its a bug unless someone can tell me if i have to click on some secret stuff in there to complete the quest? or is there anyone else that experinced the same problem? im Alliance if that in any way makes any diffrence?

Same thing happened in 2 different groups I was in. Yet I see people with the "Champion of the Naaru" title, so obviously they completed the quest. I am not sure what to do either.
