I was able to complete it before last patch, I restarted the game with the new patch and got to the point where you need to repair the door lever. I insert the lever-piece you need into the thing in the wall, the crafting menu said I crafted a "?", and then nothing happens. The quest can't proceed because the door doesn't open.
Edit: Odd, tried with my own character, with Fane, with Lohse -- didn't work. But it worked with Beast. Definitely something fishy going on under the hood.
