I've been doing a lot of Mage's Guild quests lately, and a common one is fetching research from a mage in another town. However, the quest giver warns Necromancers will try to stop me. I always arrive in the area and get in the building without seeing a single necromancer. And after I get inside and get the papers, the researcher warns me it'll be hard to get out because of all the... necromancers. So, I leave the building, head back to the Mage's Guild and turn in the papers. No necromancers. I've done this five times, never seen a single necromancer. Is this a bug or does anyone have an explanation?
