The thing, why it works, is that with auto unstuck, you'll be ported to your hearthstone location. This glitch just works, if you use your hearthstone through the auto unstuck feature, not just hearthstoning. Id done the same, flying from azuremyst isle to outlands, throguh the void. Its not just auto unstuck in a rdm dungeon, its auto unstuck in a bg, too. And this way first time get published some weeks ago by a guildmate of arrrdolf. Look at youtube, and you will find it. To explain why you fly through everything: You'll be ported to your hearthstone location, WITH the gryphon, and he will be take the fast way to your goal.
