NHF – new heroes for Heroes V 3.1.

By the way, I just tried a mod for version 60. By the middle of the game, the AI took 15 minutes per turn, and the console was filled with messages:
[Script warning!] Value was NIL when getting global with name 'NHF_Knaud_F'
(Script) ERROR: attempt to call a nil value.
I checked, and the case doesn't match.
