So, after playing the whole mission, I defeated Nokris, but blew myself up with him. But instead of respawning in the same big room, where you're supposed to bow down, xol comes etc, I spawned at the end of the slide and was blocked by a hive wall in the opening to the room. Dying again didn't do anything, only spawned my further back. I just had to redo the fight, so it's not THAT important, still a minor inconvenience.
