Zolin and Zelina - Stuck

Character is stuck at Zolin and Zelina fight. I lost on my first try, when I respawned, the NPC's will not move, they are stuck doing the ritual and chanting, they do not engage. I have tried reloading the game 3 times from outside the door, to town, and from my hideout.

I hit this as well. Resetting the instance by CTRL clicking the waypoint fixed the issue.

Same thing happened to me as well. Zelina and Zolin won't engage. Respawn at checkpoint did not work. Resetting the instance on the waypoint and rerunning the entire area worked for me as well.
