@Civplayah - you could still claim more territories.
I repeat, you cannot claim at all while at war. If you are at war the only way to expand is to attack other player's territories.
Of course, someone devious could make a secret pact, DOW on a neighbor, but each person only attacks once, while they both claim nine provinces each turn. That would be fairly obvious, but technically within the rules.
TK said you can't expand normally while at war, so this isn't a problem.![]()
