Been trying to do this quest for well over the last 6 hours, but I have just gotten error messages (same one as the Garrison), I left to my Garrison, which I could enter. I then flew back to Talador to try again, I took another route and I started the scanerio. But now there's an invisible wall all around and the NPC which I have to talk to is on the outside. My Garrison HS and my regular just gives me errors. GM ticket doesn't work form in game (never has, maybe it's because I play Mac?) and when I teleport to graverad I just get stuck more behind the wall.

Anyone knows how to fix this? Because I really want to continue...
