...I would also like to note the actions of the orange faction: I approach its castle with a scout and 1 hobgoblin, and I see that there is a hero with a full inventory in the castle. On its turn, the AI buys another hero and runs past, then the main hero also runs past, leaving me with an empty castle))
Perhaps it's the Russian version of the game? In this case, in the game, the AI does not attack the player or neutral creatures with druids, priests, and wanderers. This bug has been fixed in the later versions.
