Uh, well, a random player and a random Castle belonging to player 1, and the same for player 2.

In short, to hell with these maps. It's a real mess. For the experiment, I set absolutely everything that could interfere or is required for the map. I didn't take random heroes or random Castles. I did everything as instructed. There's a Rumour, there's a specialization, I even added armies to the heroes. Each hero has their own Castle. Everything is perfect, everything is correct, even the check says there are no errors. I load the game, go to the multiplayer games to look at the maps - mine isn't there. In general, forget it, I just wasted time and nerves.
