upd
Reinstalled the mod, but didn't add the NCF creatures. Now the game won't start, giving the error "Original game Heroes of Might and Magic V not found".
upd
Reinstalled the game, applied the mod, and installed the NCF pack from Eva. Everything is working now.
kolt_av_new_NCF_2020-05-11 still wouldn't scan; it freezes on creature_181. Even after removing the pack from data and deleting the temp folder, it still freezes on that mysterious creature 181.
