jjjoker777 - thank you for the feedback.
Regarding the lottery - yes, it's currently winnable, but there's a chance (1%) of getting some really cool stuff.
Regarding the strength of 4-8 cities, there was indeed an error that needs to be fixed. And yes, I agree, I'll add one-way portals. (Ideally, the AI's army should become significantly stronger after breaking through the outpost before the fourth city.)
asseco - how is that possible, there's no entrance?! That's strange, I'll check it now, but nothing has been changed there...
If anything, there's a trick: you can capture them before visiting the Mountain Brother, and then only enter. If you can open the console at that point and see what's highlighted in red, I would be very grateful.
The Goblins need to be unupgraded.

up: I checked the hard version. I made a few things more difficult, fixed an error in the scripts, increased the weekly growth of cities controlled by the AI.
The mine works perfectly for me, I don't know what the problem is for you, asseco.
Future ideas include adding portals for the AI, strengthening the starting hero of the AI, allowing the AI to hire many heroes, and adding active Haven heroes.

up2: by the way, for those who have already completed the map, I strongly recommend completing the quest chain with the Death Knights and the continuation.
