Hello. I've been playing skyrim for over a year now. This is my third time starting the dawnguard story quest. But this time, when Serana showed up to Dawnguard after rejecting to be a Vampire Lord, It won't let me talk to her, at all. The 'E' button I need to press won't show, and even if I press it, nothing happens. Idk what the problem is. There are some other npcs out there that I can't seem to loot, after I kill them, either. Like the one when I need to pick up the item to disable the magic barrier for the moth priest, I couldn't loot it off the guy. Just no interaction, only able to kill. Anyone know how to fix this?
