A friend and I are trying to start a quick battle via PBEM. He only bought the base game, I the big bündle. The game keeps telling Leo that he Needs the Nato module when he loads my first turn (he can preview the map, set a Password and buy his troops, but as soon as he wants to set up that massage Pops up).Is there a way to figure out, which troops belong to the base game and which dont?
