I’d say your copy of the program is completely jacked. First of all, an ally cannot take control of a friendly nations capital. If said nations capital is occupied by enemy forces then the ally can take control of territories that were formerly that nation’s, but once the capital is liberated then that country is back in the game. Under no circumstances can a friendly nation take control of an ally’s capital. In the situation you are refering to the British would lose no money becuase Japan retook Moscow.
