Mod requests (orders).

I wanted to play the original "Heroes of Might and Magic" and "Hammers of Fate," but I encountered an unpleasant bug. Is it possible, and could someone fully implement a mod for all the campaigns? It was taken from here: https://disk.yandex.ru/d/1JRV4blS7hXAxw
Where it's highlighted, that's the original. All paths in the dungeons are missing in the mod.
