We're rebooting the servers with some more bugfixes to the way the game engine handles walk-requests, including the bug that was letting people walk during no-movement duels.

You should be able to log back in again in a moment when the reboot is complete; we're very sorry for the inconvenience.

This isn't intended to be the week's update. That'll come later in the week.
