I ran into an issue today where I couldn't interact with a quest object in Vet Stormhaven. I logged out, thinking that might fix the issue, but now whenever I try to log that specific character back in, i get a verrrrry long loading screen that ends with a "An unknown error has occurred" message. I can log in all other characters on my account. I've disabled my addons, I've restarted the game, I've rebooted my system all to no avail. I've got a ticket in now, but I don't hold out much hope for anything other than a canned response.
Has anyone else seen this and if so, is there a workaround?
