I created a thread on general forums about this issue. Uh, impossible because I was executing a trade when it happened.

At this time my account is being cycled out of the game

"Booted from world as you logged into onto Server Cannith." Substitute Cannith or Sarlona as those are the only two worlds I logged into today. And I cycle between them, or I get the message I am booted from world because I just logged back into that world.
