I don't even see the reason you would log in at the same time with more then 3 chars
I myself hardly do it with 2, most of the time with only 1 char.
But anyway i think the log in server is also bugged, right now only 158 ppl online on the server it says, but i can't get in. It keeps hanging on char screen.
Either that or a deadlock i mean
Still, i'll keep on trying till i can get in again
