I didnt have any problems until yesterday evening and it seems nothing has changed till then.
Can't believe SE didn't see this coming? Easy reason .. during beta the servers never run longer than a day or two without reboot. Still .. this is a major error in the development process. If they don't fix this fast there's no doubt that this game will destroy SE and I'm not exaggerating at all!
I believe however (now that i thought about it over night) that they should be able to make some kind of afk-logout-system pretty fast. At least a very basic one where you lock out after x minutes of inactivity. They have the function to logout and some sort of timer should be present in any framework. So .. maybe 20 lines of code and you are good to go.
SE give me the framework documentation and I'll do it for you :P
