Problem: By accident i killed Stablemaster Diana and Hayden the Madshot .. before i took this quest. And now they don't spawn anymore soicant continue this quest and questline. I need only 1016 reputation in the Proudmoore Admiralty to get Revered. I did all this with quests alone .. so its a longgggg ridesofar. Can someone help me ingame ? I tried to make a ticket but the qame gave a fail when i wanted to make a ticket ingame.
