That's it! I'm calling out on Arthmoor.
I was able to fix it by using EFF mod to force recruit Delphine, then using the power leaders teleportation while standing next to the wall.
Oddly enough she didn't take out a torch but the dude started talking again, walked to the other torch, and I was able to continue the quest line.
That is what I did and it worked.
Now i have multiple of him lmao
I just teleported delphine, (cuz she wasn't there) (with pickrefbyid 13485 then movetoplayer), and the quest continued pacifically
I'm on Xbox as well. I was getting the issue where Esbern wouldn't talk about the wall. Delphine would step inside the temple but wouldn't move up the stairs. The issue was that even if she had a torch in hand outside the temple (tried it day and night) as soon as she stepped inside the temple it would unequip. So she couldn't light the sconces going up the stairs or the final one at the wall that allows Esbern to say his bit. Like a few other people have suggested the fix was disabling the USSEP.
When I went in the temple he was stuck in the wall at the entrance. I waited an hour and it fixed it but Delphine was missing so I went in the previous room, waited an hour, went back into the other room and she was there and Esbern was talking about the wall
All I did what download the cheat room. Set her to kills me then brought her back to life and the game continued without the blazers being lit
Exit to Karthspire and return to the temple to reset Delphine.
What do you think?
