That's a true shame, I really want this to work as I've been making my own World War 3 story and North Korea has a war pact with Iran. I really hope the modder comes back to this, I believe it's something to do with the change of weapon files, so it doesn't sound too complicated for modders. For now I guess I can make a Plan B storyline where North Korea is being choked by South Korea in a counterattack :(
