If memory serves, this is a puzzle you can only save between rounds. Either way, I have a save in amateur mode. I keep all of my saves on mega.nz, it won't let me get the direct link for just that save, so here's the link for all of my saves for that game: https://mega.nz/folder/115h1YhI#ytXPtchEvbnnsUEeYcSGTg/file/thpU0YoQ just go down to the one titled Tie Breaker, right-click and click download. Then just put it with your saves for this game and you should be good to go
Glad I could help and congrats on finishing the game I started keeping my saved games uploaded incase I saw a post here where someone was stuck and needed a saved game to continue (I do that instead of keeping them on my PC or my portable drive so I don't risk accidentally deleting them and not having them if someone needs them). My backed up saves are in junior/amatuer mode since I have not played many of the games in senior/master mode
