I challenge you!

I installed the NHF mod and decided to play your map. On Veteran difficulty, the scripts don't work (there is no bonus to growth, and the enemy easily captures my Castle without breaking through the outposts). Version 1.2.1; on Warrior difficulty, everything works fine, but it's too easy for me. Question: Is the problem specifically with your map or is the NHF mod to blame?

I mentioned in the thread about the NHF mod that it currently only supports standard developer maps and the HoMM generator, meaning this map isn't supported by the mod yet.

Removed the mod, the problem remains.

The save files store old data from previous game sessions of the map. It is necessary to start a new game. Also, you need to remove unnecessary maps and mods from the folders.

Uploaded a new version of the map that allows playing with the NHF mod. - Иду на Вы! 1.2.2

P.S. If someone's map doesn't support the mod, you can contact me, and support will be added ;)
