^That's cool. When the club members were coding up their Emotion boxes, I had them initialize/reset their mini-games from an Action Button too. Then when I discovered the Level Starter firing in my anchor box, I just added the Level Starter on each linked box to push the corresponding button.
It's a cool strategy to assign the initial state of the hub world from an Action Button and simply pushing that on the final save. It's a clean separation from settings you want on the re-load returns to the hub.
