Did you try to restart the game and reload from before entering the room?
I actually managed to enter there quite peacefully despite the whole camp being alerted (I botched the assassination of Minthara)
Yes I have and should have stated that. I've gone back to my oldest save and still no bueno. I've also left that room with the door and explored more, came back to the same thing. I'm walking around peacefully, no aggro whatsoever. I'm new to the game but not this genre. I'm at a loss. Might just have to restart this, but I hope not.
