Verzhak’s company is on the champion.

Hello everyone. I know it's not good to revive old threads, but I couldn't find a more suitable topic. I recently decided to replay Heroes 4. I started Lysandra's campaign on Master difficulty and easily completed the first mission. It was too easy. I started again, opened the entire map with a cheat, and started watching what the AI was doing. And it's acting strangely. It's building something, gathering something, but it's doing everything extremely inefficiently. At the same time, I remember how it used to make me rage in childhood on "Normal" difficulty (which is right after "Beginner"). It doesn't seem like a bug; the AI even uses portals to attack. But its indifference to mines and failure to use the obvious advantages of a level 24 hero are concerning. What do you suggest? I installed the game clean, without any add-ons or the Equilibrium mod, but I definitely remember that even without them, the AI was good in childhood and by the end of the second week, it would try to attack me with a large army. Could it be due to Windows 10?
