Guild Wars 2

I was doing SAB W1Z2 TM from about 2 hours and when i reached this checkpoint http://www.youtube.com/watch?list=PL_mhG6YlEiUKn8ebSmGF8qH9Rg9OaJ4OD&v=XJMwmu-bslw&feature=player_detailpage#t=325 (time marked on someone else video) and minimize game like dozens of times before to check the way forward, and when i maximize game first thing i saw it was SAB loading screen and game decided to teleport me back to SAB Hub! WTH I just lost about 3 hours and i need to start all zone again. I was so close to the end, one shop to visit and one boss to kill but not today because of some kind of black magic. Thanks alot Anet -.-

Had the same problem in world 1-2.
I minimized the game to check sth, came back few seconds and bäm, SAB entrance.
I wasnt sure if some dirty monkey hit me or not, but after re-entering i had 1 life left. So i was sure i got kicked.
I was maaaad as hell.

Happened to me yesterday as well.
