Atziri Pinnacle Fight bugged out after getting her down to 10% hp

After getting atziri down to 10% hp, she bugged out and cannot be damaged any longer. She is just frozen in the middle, constantly attacking with blood. I have a video of her glitched out. I also have a video of after I tried to exit to character select and come back, she is still glitched out and then a second copy of her model appeared. And I have a video of respawning at checkpoint, which then lets me reenter the temple, but she is still glitched out. Dying obviously closes the temple and the only thing I can do is die. This is a disappointing bug, since I didn't even obtain any loot. It was my first time fighting her after literally playing to level 92 without being able to unlock her at all.

I had the same thing happen to me, Boss fight was essentially over after going through portal and getting her to 5-10% health in serpent form. Doryani went back through the portal and I was stuck in the room with Atziri, I respawned at checkpoint as it was the only way to exit. I went back to Doryani and he said I could take what I wished, but none of the chests were lootable. After several minutes of clearing all the rest of the rooms talking again to Alva and Doryani again, I left the temple. Upon reentering all my progress was reset. Very disappointed.

Same exact thing happened toe just now. Am I screwed? I just beat her and Doryani said go through the portal but there isn’t a portal. I hope I don’t miss the loot but I think the only way is to respawn. Love the game but that is a bummer haha took a long time to finally get to her. Really cool fight though. I hope they fix this bug
