Walkthroughs for custom maps.

I would like to ask not only you, but everyone. Map editors often "sin" with such a trick when "paths" are hidden. Maybe someone is delighted by this (and tastes are not to be argued), but are there any programs to "see" these "invisible paths"? Experienced players, for example, know that with three or more bodies of water, various objects, or volcanoes, and even in swampy areas, the map editor can create such a mess that you don't even want to play, even a little. I'm just used to playing standard missions where you don't encounter such "cool" tricks. How do you deal with these problems?

Maybe I'm missing something, but you can check the map's traversability in the editor - there's a red-yellow grid for that. If you can't "feel" the map, you can see from the cursor whether there's a path or something is blocking it - you need to pick it up first. Sometimes it's difficult to check - for example, if something is behind the city. In the game, viewing the land or air will help - it will show whether there's a resource or artifact there, or just a dead end, no road. In my opinion, this is normal - it looks much more stupid than the WoG tricks, when one object looks like another (for example, a witch's hut looks like a mine - you want to get a resource, but you get rewarded with an unnecessary skill).
