Manoki, The Chosen bugged

During boss fight the boss bugged and stopped moving or attacking. I could damage it until around 20-25% of its HP and than it became untargettable as well.

The fight did not progress any longer. I have a screen recoding of the proccess showing the bug and me re logging to the fight by resetting the instance.

Same thing just happened to me.

HOw did you reset the instance? i'm stuck forever in the arena, restarting the game just beings me back?
