I have the quest "Scroll Scouting" for the vampire side, and I'm being sent to Winterhold to find info on the whereabouts of the dragon scroll. The problem is after I start to talk to the ugly orc in the Arcaneum, it starts the quest for Parrthanaxx in the main quest line. The one where you gotta find the elder scroll so you can see back in time to learn the dragonrend shout. Afterwards, I lose the quest to continue the search for the dragon scroll. So basically I'm screwed, lol. Dunno what to say, this is but one issue from a huge list of glitches I've run into. I'm really shocked this xpac was released from beta. Also disappointed.
