The Broken Tusk Inn had this bug where if you did the intro quest for BfA on a Zandalari, it would lock the inn into some kind of phasing. I submitted a ticket at first, but it hasn’t been responded to in years and it’s getting a little annoying. The only “fix” I have seen is syncing with someone who has the intro quest so you can hand it in with them, but I rather the company just fix bugs like this.
