Cuachic Vault Boss Fight Never Starts

Zolin and Zelina just say words and never start boss encounter.
Reloading last checkpoint does not fix
Bouncing between checkpoints does not fix
Alt+F4 and relog does not fix

Had to go to waypoint and reset zone to fix

same, had to run back entire zone.

sadness and sorrow

Same thing happened to me.

I don't know if this adds context or not but I managed to remove one of the two bosses from the fight and got killed after.

Bug Report ID: #250669522

Boss fight started once, killed priest, died to priestess. Fight would not start a second time. Respawn at checkpoint. Still nothing. Tried leaving boss area and coming back in, nothing even after several minutes they just keep talking.

This also happened to me. I killed one of the bosses and died. Now the two are just stuck in dialogue with each other, no spawning of boss.

This happened to me too. Killed one of the bosses, died and now the fight wont start. wild this exists
