I boosted this character to 110. I skipped Jaina’s journey to Kul Tiras and the escape from Tol Dagor with Flynn. Yet, when I fly to Boralus, hearth to the Snug Harbor Inn, or take the portal from Stormwind to Boralus, I get sent to Tol Dagor without any characters to interact with. Thus, I cannot escape from it to be in Boralus. I can hearth to (new) Dalaran and such, but I cannot return to Kul Tiras.
Had the exact same problem. Turns out the quest to escape from Tal Dagor quest got put in my quest list, if its there just abandon it and things should return to normal.
Similar issue but mine is that I can’t even log into the character as he is stuck in a loading screen loop. I also skipped all the intro scenarios having done them 4 times already on other characters. Submitted a ticket to see if I can get the issue resolved as using the character stuck self help tool did not resolve the issue only delayed it until I attempted to hearth to Snug Harbor Inn.
Ok I had this issue as well first look in your quest log and abandon any of the quest that are related to the scenario, mine began at meeting Katherine Proudmoore that should have you in the phased version of Tol dagor without NPCs. At this point I had to abandon the escape with Flynn quest which then made it possible for me to hearth out and start normal questing again. Hope this helps anyone else that has run into this bug.
