When i enter the realm to kill the mobs only 1 or 2 of them are moving the rest are frozen. I tried restarting the quest 20 times changed server, closed game, forfited quest 5 times, this is not even in the known issues for 2 weeks now 3 with the upcoming week.

I encountered same issue, still haven't found a way to solve it. Support has been of no use so far.
