I'm sorry but my brother in law's main quest is broken at where you have to find esbern, has been since december, still is. He emailed bethesda, they didnt do [censored] about it, So, glitches that break MAIN QUESTS are not priorities in your book, cmon man, the expansion's quest line is broken because of that glitch, how is it not a priority?
Expansions questline broken because of esbern?
Dont even see how that is possible. You do not even have to do the MQ for the expansion, you just have to talk to the orc in the mages guild or the guy on the island.
And even so, thats why you should always have backup saves.
