NHF – new heroes for Heroes V 3.1.

Hello everyone. Sorry for disappearing... for years... and that the question will be somewhat off-topic. I simply didn't have time for anything... Now I decided to remember the game; I used to only complete the Campaigns and some scenarios. I didn't play on simple maps. What a disappointment... The AI didn't create any problems for me, and this is on the most difficult level, "Hero"... I even set up opponents of the same race and closed off slots so that he would have more Castles. Nothing...((( This wasn't the case in the third game. Who can advise me on how to improve the AI? I browsed the forum, but I didn't really understand. Somewhere it's for version 3.0, another mod only prevents them from fleeing from battle, and that's it. I understand that you can't turn a computer into a person, but playing multiplayer with real people for hours is also not an option... Naturally, it needs to work with version 3.1 and NHF.
