Recently we disabled the downgrader due to a bug in the upgrader, which was causing some boards to end up empty. We've fixed this bug in the cases we have been able to test, so we have enabled the downgrader again. If you have boards made empty by the upgrade, please run the downgrade and re-upgrade them to restore them. As before, the downgrade will revert all boards from back to their state before the release of Chimera. If you created a board after the release of Chimera, it will be unaffected. This patch also fixes the bug where, if a board crosses a certain number of lights, all the lights go dark. See you all in the next patch!
