I'm having a problem with the quest Innocence Lost. I talk to the boy and get the contract to kill the Grelod the Kind, and I went and killed her. But, the quest doesn't acknowledge she's dead. Her body on the floor still has a quest marker, and my objective is still "Kill Grelod the Kind." I tried redoing it several different ways including killing her before recieving the quest, but it won't work. Help! PS I have already tried waiting, restarting, and leaving the town...
