I am doing the quest for Solitude's court wizard. She asks me to kill the vampires and their leader inside Pinemoon cave. I had already cleared the cave before initiating the quest, and when I go inside, there is a quest marker on the ground(presumably where I killed the leader before). But there are no people inside. Usually if you try to initiate a side quest, such as this, where I previously cleared out the cave, there would have been an option to tell the court wizard that I already took care of it. What's going on here?
Also, is this a quest that must be done before I can purchase a home in Solitude?
