BLITZ TOURNAMENT

that is, navigation bonuses have become land-based, I understand that it's wrong, but the rules don't prohibit it.

Hmm... I quote the rules:

General Rules of the Blitz Tournament:
5. The use of any cheats and bugs in the final run is prohibited.
i.e., it is forbidden to:
...
- use navigation bonuses on land.

I'm curious, what do you mean by the absence of a prohibition?... It is necessary to check whether the marine move points remain in the hero's reserve when fleeing and subsequently buying them back... If so, then this is a bug and using it is prohibited.

For the future, the "Shlyapa" (likely referring to a specific strategy or exploit) needs to be thoroughly analyzed and broken down into points... :) Not everything there is a bug, as it may seem at first glance, but at the same time, there are bugs that are not visible to the naked eye...
