I would assume it is a vid card driver issue you are having maybe, upgrading that usually helped alot of games out in NT4, but some just plain would not run.
If I remember right though there was a reason why Japan didn’t land in Manch I think it was b/c there was a counterattack possible and so GWS choose to go for either SFE and Kwan or all to FIC.
England can wait. When you take Russia you get it’s coin. That should give you whatever you need for England. Plus you’ll prolly win the game with an ipc victory (unless UK is about to march on Germany).
By t3 I have like 35 inf plus whtever in kerelia. I welcome the attack! I exagerate a bit but if Germany attacks Keralia I suggest earlier unless USSR does something stupid. Or later if Japan is threatening from the other side.
