Absolute power.

All maps in the Maps folder must be identical for both players.

It worked, but we can't really play. When playing through Hamachi over a local network, there is severe lag. Especially after the computer's turn (which, by the way, takes at least 5 minutes on the first turn), you can't do anything.
For example, the computer makes its move, and then my turn starts. To move a hero a short distance, you have to wait a minute or two. It's simply impossible to play like this. These problems occur on other maps as well, but the smaller the map size, the less lag there is, although it's still unplayable.
