I seem to be stuck. I am supposed to get Pops O'Leary and also some plans from his henchmen. I have eliminated all who wander in this area, have not found the plans, and cannot open the door upstairs in the factor. I read something about a knock to get in? I went into the two areas behind the factory but cannot get into anywhere there either. Can any one help me? I don't want to leave as it is an instanced area and I would have to start over.
