“Best map for Heroes of Might and Magic III” (2007).

..........they say the map isn't working :(
maybe it got corrupted during archiving? I'll try again...

Vanechka, the problem with your map is that it uses objects from WOG. To fix this, you need to open the map in the editor, then press ctrl+f (search) and find grassy hills. Then, delete them and, if necessary, replace them with standard obstacles.
