I am stuck in elder knowledge. I have completed the discerning the transmundane quest. The marker is stuck in Urag. I have the scroll, tried to go to Paathurnax and read it but the game wont go on to the next phase. I have the dawnguard guest in the phase that i should find another elder scroll.
*if* you are at the point of reading the scroll and he just flies off while you are talking to him, just sit there. He is still talking, even though you can't hear or see him...He eventually comes back down after a couple of minutes and the quest *should* continue as normal.
