being disconected for losing power? this system is still broken needs major fixing I got one for network timing out so not the first time
I rebooted system just happen to wait a while sign in and opps can't do ST'F's

And then what is to prevent people from simply making a cold shutdown of the game and go back in?

Na... it works. The game has no way of checking if you are coldstarting or loose power... Fine as it is.

I have to admit that it concerns me as well. For example I;m currently at a local mall using Anthropologie's wireless. I know that's going to disconnect twice an hour and make me relog back in so doing a STF here is out of the question.
