The game locks up and won't let you get to your keep, you can't shield when it happens and you loose your troops and resources, GOT will not do anything to help you with your losses, I was not able to login for 2 weeks, glitches across the game and to advance above level 10 get out your wallet its not free to play after that, if you do get above level 10 you will be attacked by all the high levels players just to burn your keep and kill your dragon even if you don't have resources to steal.
