Castle of Knives Salim not there

Platform:PC

Do you have any mods? No

Please explain the issue is in as much detail as possible:
No matter how far back my saves go, or how I approach the Crag Linnorn, Salim is not there. When I get there, the camera pans SE then back. Salim talks, but I ask one question and then have to fight the Crag, no matter how I kill it, there is no crown and there is no Salim. I read that this has to be finished to stop The Fog event. My kingdom has died, I had to put it in invincible mode.
