Glowing hearthstone locks your character

The past 2 times I've used glowing hearthstone to return to the Garrison I've been disconnected and cannot login to the character any longer. Yesterday when it happened it fixed itself a few hours later, but today I've been unable to login after hearthing to garrison for many hours.

My character has no location under it on the selection screen, but when I try to enter world with it, it loads all the way up to about 95% bar, then pauses and sits until it disconnects me.

I warn against using this method to return to your Garrison unless you want to lose your character for the day.
