OK so i have no idea if this topic is still payed attention to anymore but I have a problem with Dawnguard. When i enter Valercia's study the quest arrow remains where it was and the chasing echos quest doesn't proceed. I have had Dawnguard for a while and i am wondering what is going on since on all the other characters i did this on didn't glitch up like that. If someone can help me with this that'd be VERY nice this is PC Dawnguard by the way.
