I recently started the game post TWW and leveled fine through Exiled Reach. Did the questline up to ‘Home Is Where The Hearth Is’ and I believe immediately after finishing that, you get the quest pop up directing you to Dragonflight. The problem with this is that pre-TWW, this quest would complete and point you to ‘An Urgent Meeting’ where you’d talk to Captain Garrick in the throneroom with Anduin.
The bug is that when you pick up ‘Rise of the Brotherhood’ and go back to Stormwind, it’s stuck in the phase where you would talk to Captain Garrick, go through more stuff until you get sent to BFA by talking to Jaine at the docks.
It seems after you complete ‘Home Is Where The Hearth Is’, it still thinks your character is now flagged for ‘An Urgent Meeting’. This is probably where the bugged phase is. I’m just trying to get Loremaster for the Vanilla areas.
For now I’ll just keep it in my quest log. Hopefully it gets fixed. Thanks.
