When use Garrison hearthstone in 20th area it will not take you to garrison but into the sky.
Hang you in the sky and never drop down to earth.
It stuck me twice.
That’s ok using the Stormwind portal in caverns of time drops you in fatigue waters off the coast. Been awhile since I’ve seen the sky glitch. Is it over Alterec by any chance? Or does it stick you in Alt Draenor somewhere?
Stick in the Tanaris air, and if you reboot game it will switch to Draenor.
Me and a friend noticed yesterday that all the different hearthstones and their fancy graphical effects, can only be seen by the player casting it, everyone else just sees a player waving their arms around in the air like an idiot until they disappear.
The Orgrimmar portal occasionally takes you to fatigue water off the coast of Pandaria. Figure that one out.
