My account is stuck logged into the tekkit server! I can't use my minecraft account on any other servers because it says I'm "logged in elsewhere." I've never had this happen to me before.. Very weird. I assume that the server restart in a few hours will fix this for me, but I'm wondering has anyone else ever experienced this error? How did you fix it?

*Grumble grumble* I was making good progress on the sorting machines, too! Well, I guess it's time to call it a night.

crash can cause players to be stuck in the server
if this happens again check the livemap and see if the clock keeps reverting after 3-4 secs
seems atm it still is down
