Stuck after being Summoned.

So, I play on Icecrown, the WotLK expansion, and whenever someone summons me at a summoning stone in front of an instance, I get stuck mid-air next to the stone, running in place. I cannot log out, hearthstone, I have tried /reload and Auto-Unstuck, nothing has worked. The only thing that does work is me exiting the game completely, but then it's back to the queue again.

Happened to anyone else?

Happens every time I fly over Argent Vanguard in Icecrown. And sometimes after using flight paths. If you get it when summoned, try to get summoned again. If that doesn't help, exiting game seems to be the only way to fix it. You were supposed to be able to log back in without queue within a few minutes of logging out but I am not sure if that still works.
