That's odd. Game's been working fine for me (PC EU) but I've been logged in for a couple of hours already so maybe that's why. Although I'm jumping between the toons and still no issue of logging in or out.
I spent the last 4 days without playing because tuesday maintenance broke something about the capacity of the game to send me my access code to my original email...
US hamsters are asleep... EU hamster heart monitors are not connected to overlord hamsters in US. Its a silent flat line that might or might not get a maintenance. They will probably write that they took the servers offline to fix the issue ;-) Like the online server is making so much difference at the moment.
