France offered to hold their action so that Germany could go immediately, thus allowing Italy and Germany to coordinate more fluidly, instead of interrupting to state they were doing nothing and causing a multiple day delay between Italy and Germany.
If the players agreed to the change in order, the agreement should stand. Why should the Axis assume France would not make the attack if the order has been changed. Have the online moves been being submitted as if France was going in it’s original order?
