Command doesn't seem to work, doesn't detect a restart is scheduled, unless I'm using it incorrectly?
Can just alter the config, though rather not have to remember to revert.

That command only works for manually scheduled restarts via the schedule command.

The one you're looking for to prevent a config scheduled restart is the suspend command. Use that, once the time passed the config scheduled restart it will put a note in console and then continue to the next restart.
