The NPCs don't sync with vanilla players. They do with other players who got the mod but there's not much meaning in the mod because actor sync in mutiplayer can be quite buggy. Like you got yourself an army, but like 20% of it failed to sync and the other 80% disappeared after third cell load because of some glitch.
