Walkthroughs for custom maps.

I don't understand, is this intentional, or is it a mistake by the author? Between the two pink cities, the passage is blocked. There's a guard stationed there, and a road, but the obstacles are arranged in such a way that it's impossible to pass.

I checked in the editor: if this is cell 122,119, then it's almost certainly a mistake, as the map is built very densely, and it's not uncommon for adjacent obstacles to not look like that in normal mode. The pathfinding mode always makes these problems visible.
Regarding AI behavior: give me some clueless Necromancers, and I'll probably beat this map too... maybe. :)
