OK, so thnx to pokie, I now understand that each country is a zone.So if Bish HQ is zone one, then all bish related fields must be created as zone one? Also what is the Zone Master box for? And when should it be checked? Also, haven't solved the hanger on the deck of CV's from sliding over the water when the CV is turning. I have added extra ships to the groups, is this causing it? And if it is,why? Someone mentioned it is the ships passing through each other. If it is,how can I solve this?
