There is a way, through the editor.
And how?
Added after 8 minutes Another problem has appeared with the mod for NCF creatures (i.e., I only have a database with new IDs for creatures and an executable to launch the game with the readability of this database) - elves, for some unknown reason, have started choosing non-existent creatures as their sworn enemies. I haven't planned anything in this topic yet, so I haven't changed anything. Does anyone know what causes this? And how can I fix it?
