Hello everyone

My problem is I'm playing the "A False Front " quest line which is for the side of the Stormcloaks. I am now at a point where I find Legate Taurinus Duilis in his quarters at Highmoon Hall in Morthall, and herein lies my problem: he is always inside the Guardhouse which is locked to me. No matter what I do I can't get to him. Tried waiting, fast travelling to other towns, loading previous saved games. The result is always the same.

I have told a friend about this and he said it's called the Imperial Bug, but he can't be sure as he doesn't play Skyrim himself.

A solution would be greatly appreciated!
