Pedro, the guy you are supposed to get the note off of, under Ars Magicana is for whatever reason, frozen and neutral. I can't do anything to him at all.
I did enter the sewers earlier in the game, and neither he or his cohorts were anywhere to be found. I am assuming some progress I made afterwards finally triggered the event, probably after talking with the local guard about Tingalf..
He was injured the first time I stumbled across this, though I am not sure how.. I am assuming if I did some careful coordinating, I could stand somewhere that his ranged men would attack me and hopefully kill him instead, but before I mess with all that, has anyone had this happen before?
I am patched and everything, and this is my first time playing the game through on hard without doing anything like duping, and other minor cop-outs - I would really HATE to have my game screwed up to the point where I can't solve a particular quest, etc.
