Missing in Action Northwatch Keep Bug

I give the Thalmor guard the Imperial Order. The game says to follow him into the keep, but I get attacked when I do.

That shouldn't be possible unless you've done something to aggravate them such as assault or theft. The one time I tried that method with the patch installed I was able to go in and rescue Thorald and come back out without any Thalmor becoming hostile.

Are you using mods, and if you are then what kind of mods do you use?  Post your loadorder.

 

Also, try to go back to an earlier save, a normal gamesave and not to a quicksave/autosave and re-start the quest.  Before you either installed a new mod(s) or uninstall a mod, which is NOT recommended to uninstall a mod(s).

I am using no mods other than the Unofficial Patch. I reset the quest and went through it again. That did not solve the problem, so I just did it the violent way. If I start another playthrough, I will go through the quest again and see if the problem persists.
