Interesting glitch, This was way-back befor outlands. My husband and I went to take a flight from Hinterlands to.. somewhere, and both of our griffons glitched. You could fly anywhere, but not higher or lower. You couldnt take damage, and you couldnt dismount. The flight pattern was erratic glitching backward over and over at about 15fps. Glad I didnt loose these caps.
Take note - map shows us in hammerfall, to this day you still cant fly in the old world.
