With the setting off the device is made exactly as before the mode existed, so the mode cannot change anything for a player who never turns it on. Turning it on in the menu then takes a restart, and the row says so; in a run that started with it on, changes still apply at once. Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>
