MCE is closed, the app has to disable engines 1 and 2 (my keyboard pattern disables engine 3, then restores it when it finishes). The app should re-enable them when done, but it doesn't. Restarting mce should restore the LEDs and haptic feedback.
stop mce && sleep 1 && start mce as root in terminal
