Here is an excerpt from your rules.

"7. In case of suspicion that a player is cheating or has other malicious intent while playing a map, it is necessary to save the game before each significant event (e.g., before a battle, before hiring another hero). The result of a player who did not play fairly, as well as the player who did not send their description (saves) on time upon request from the tournament organizer, will be annulled, and their further participation in tournaments will be impossible. This will also negatively affect their reputation."

But there is nothing mentioned about saving the game every day! So, does that mean it is not necessary to do so?
