Well. after more play testing I found a problem.. Having some things prebuilt breaks the AI when the computer plays Germany or Japan in the scenario. I have fixed this issue by eliminating the prebuit structers aside from the capitol cities. I am doing a bit of tweeking and will upload a new version soon. I also plan on digging into the AI scripting functions a bit and doing a new version.
For the moment, if you play as 2 players, I would recomend playing as the chinese and the russians or as the germans and the japanese. Mixing in other ways would prove to be very unbalanced as the person who plays the northern nation would have active ally support and the other player would be on his own to defend another player and the computer.
