The below issue was resolved with a server reboot. Hopefully the banned players can join me soon and enjoy the game.
I was enjoying the updates on official server 1818 and got disconnected. Since then, I get an authentication error when I try to log back into 1818. Funny thing is that I can log into every other official server that I have characters on, but 1818 gives me an authentication error. Please take a look at this as the opportunity arises.
