As far as I know, if the save file has already reached the organizer, you can no longer submit a new one.

PRIZRAK, please clarify, as there is nothing in the rules that says it is forbidden to resubmit a save file with a completed game (if you managed to improve the results compared to the first time), and that the second submitted save file will not be taken into account by the judges.

And a suggestion for the future (sorry if I'm posting in the wrong topic) - to schedule the end of any tournament for 12:00 on Monday, as most players have the main time to complete the tournament during the weekend (Saturday and Sunday).
