Heya, I forgot that I was world visiting on a different world. I was there mainly to hang out with some friends of mine. But problem I can no longer log in....

When I try, I'm told the world is congested and Visitors are unable to log in... So it won't even queue me? Okay, whatever, I'll swap back to my home world. May take more than 1 minute to do but whatever... It won't let me go back to my home world...

I can't log into the game. What is this scam?
