NHF – new heroes for Heroes V 3.1.

I can't upload Psatkha screenshots; there are no problems in the Maps folder, as I mentioned earlier. UserMods and data have also been thoroughly checked, and everything is fine there. All versions from 1 to 56 worked normally, and nothing new has been added or deleted since then. Starting with version 57, the mod started giving an error with the message (presumably, something is wrong with the mod itself; I ask you, the mod creators, to check your mod; there seems to be an error in it). My friend had a similar problem with a different game; the mod also didn't work; it turned out that the mod interfered with the game system and replaced certain elements. Could your mod also be interfering with the game and replacing certain elements? I read a thread here, and it seems there's a problem with portals due to a mod; if I understand correctly, please check everything; I'm really asking you.
Dyrman, thank you for suggesting the programs.
