Yea that whole area is crazy buggy for me. I ran it to the burning building and talked to the politician (through a door) who thanked me for saving her and asked me to save a Duke? I then got a quest completion for saving a man from under a burning pillar that I never saw. Didn't seem to break anything else but so I shrugged my shoulders and moved on, but I was very weird, I'm not sure what was even supposed to happen there.
