NCF – Extended list of Neutral creatures.

Guys, I desperately need your help. I've searched half the internet, but I still can't get this darn NCF to work. I didn't install any packs (there are just too many creatures for me), but I downloaded individual creatures directly. I downloaded NCF_core and put it in the right place, as well as the creature files. I launch the editor and the game through the NCF launchers, but nothing works. In the map editor, I can place the creatures, and they appear when I launch the map. However, the map generator crashes, and the new neutral creatures don't appear in scenarios or campaigns (I even ran a test, forcing the entire map to be filled with random units, and not a single new neutral creature appeared). The strangest thing is that the mod for creatures from Dark Messiah and Heroes 7 (by Zahar0z) works perfectly. New neutral creatures spawn in campaigns/scenarios, and even on generated maps.
