Ok fine then UK builds a factory in Spain and US lands to support it till the factory is pumping out. Game broken because once those German subs are dispatched, UK needs nothing because Spain is in reach of Medd and Germany. I know after playing it many times back then that it had some huge bug like this , which was always game over for Axis.
To have no limits on what can be placed in your newly built factory is a game breaker in any AA game
