Current questions and answers regarding the map editor.

Good evening. Could you please tell me how to set the desired range or the desired number of neutral creatures? Perhaps I'm doing something wrong. I click on the unit, select "Custom," set it to 10, then set "Range" to 19. When I check in the game, sometimes it shows a range of 20-49, or even 50-99. Is there a way to fix the numbers I set?
