Flying in to & out of Ghostlands glitch work around
If you're experiencing a glitch flying into or through Ghostlands and can't move when you land, here's a work around.
Once you go through the portal/gate between Ghostlands and Eastern Plaguelands and the load screen disappears, log out then right back in again and you should be fine.
I just tested this 3 times with success, it's funny coming out of Ghostlands, after you log back in you're no longer on the Hippograph, free fall for a sec then appear on the Gryphon. I do anyway.
Hope this helps someone!
