Guild Wars 2

Problem: Upon losing internet connection the game immediately disconnects you. (This even happens during loading screens)
Once you’ve been disconnected, the game is supposed to close down automatically, but instead it becomes stuck with a pure black screen (or white, if you were loading)
Only way to quit the game is to Alt+F4 or forcibly kill the process.

Steps to reproduce:
Black screen
1) Load the game (Go to character select)
2) Disconnect from the internet

White screen
1) Load the game
2) Choose a character and start the loading screen
3) Disconnect from the internet before it finishes.

I agree, this is an annoying process, instead of being left with a black screen we should have the option to return to character select instead of completely restarting the game every time.
