[Solved] I have the Dragon Scroll, but it isn't satisfying a quest

[Briggs]

I'm on Seeking Disclosure in the Dawngaurd main questline, and have both the Blood and Dragon scrolls. However, the Dragon Scroll that I obtained during the main Skyrim story questline isn't satisfying it. I've tried dropping it and then adding it back, but it still isn't working.

you need one more scroll

[Briggs]

Yes, I have the Blood Scroll. That one is ticked as completed. As far was the quest script is converned, however, I don't have a Dragon Scroll even though it's sitting snugly in my inventory.

You need three scrolls for the Dawnguard quest. Blood, Dragon and one I can't remember. In my playthroughs, sometimes if I already have the Dragon scroll when starting Dawnguard it shows it in my inventory but not that I have obtained it in the Journal. However it has never prevented me from completing the quest.

Serana has the Sun scroll, her mother has blood scroll and Dragonborn has the Dragon scroll

[Briggs]

I have all three. You can't get to this point without getting the Sun Scroll. I can't proceed with the quest line because the game thinks I don't have the Dragon Scroll.

I assume you've tried going to Dexion with the scrolls (the next stage after obtaining them both)?

What might help: goto the winterhold chief librarian guy, sell him the scroll and immediately buy it back.

Selling the scroll and buying it back worked. Thank you.
