Have a similar issue, made a thread before I saw this one
Edit: Has anyone tried deleting and restoring a character that cannot get any of the BFA quests to see if that works?
Edit 2: worth noting, not sure if it matters, but this is an allied race (dark iron) made before prepatch (many months prior), left him a little over halfway, then post level squish and prepatch I leveled him to 50, so this isn’t a character I made during the prepatch.
