How can you explain the fact that the lower Sorcerer's town is also red, if there is another town on the way from the red castle to this town, which remained neutral until the end, although the demon with djinns ran past it?
On the map, there are almost imperceptible gaps in the obstacles, i.e., we have an almost closed territory, and the entrance to it is guarded by neutrals. But you can get there without touching them. There is an obscure path to this territory, which can be noticed either in the editor or by selecting your hero and clicking the mouse in the center of this territory.
Perhaps this is an error by the map creators, or perhaps it is their intention. The AI uses such loopholes, bypassing the neutrals (verified), therefore players can also do so. Otherwise, the AI goes there past the neutrals and takes the town, and what about the player? Should they necessarily kill the neutrals beforehand? Especially if you now have to fight the AI for this town :) That's not fair :) And in reality, there is a passage, it's just not visible to the player. Therefore, you need to look more carefully, and even better, click everywhere with the mouse :)
