NHF – new heroes for Heroes V 3.1.

I feel bad about the hero; on some maps, it can significantly impact the game.
Regarding the neutral creatures, I'm still not sure because I didn't see what was on the other side of the passage (there's a chance a hero was standing there). The map was made in the map editor, played in multiplayer, and there are no other mods or map mods. The map was processed through nhf_ms 0.9.
Another question: how playable is the mod in single-player now? Because I remember that not everything worked properly before.
