Hey there
So I haven't actually started the Dawnguard questline, but I have completed the Aetherium quest and have some other Dawnguard enabled items in my file, along with one Drain Vitality Shout. If I deleted Dawnguard to say, avoid a bug invovling another Drain Vitality Shout from appearing in my game, I'm sure I'd lose all those items at the minimum, plus the word I've already learned for Drain Vitality. But would I be able to regain all of that once I reinstalled Dawnguard to my save file? I mean by redoing the stuff like going back to that word wall, redoing the Aetherium quest, and reforging some weapons.
Thanks
