Yea I’ve reloaded like 6 times and I’ve used shouts and all other types and stuff but everytime his health goes down to zero he becaomes unresponsive and heals, not attacking or defends and not retaining damage just healing and you can’t interact with him after he heals and you can’t kill him I’m really angry and confused
Had this problem and as far as I could tell it only happened when he telleports and then I guess something glitches and he can’t die. But if you just reload it should work after a few times. I tried with Auriel’s bow too and didn’t work for me
so this happened with me and alduin, on the throat of the world, but never with harkon so this isn't a guarunteed fix. what i did was reload a save to before the fight happened and waited for alduin to aggro. do this with harkon and it may work.
i know this is an old thread, and i'm posting this just in case others look back on this for help.
I had a different issue revolving around the final battle with Harkon. Right before Harkon was about to die, my game crashed. I probably restarted the fight over a dozen times, all with the same affect. I'd completed the quest before on an old save, so I'm not exactly sure of what happened. I've started over on a new game, but I'm afraid to try again in case it happens again. What should I do?
