That's exactly what a Cylon would say!
All is dust...
From the Stuntkite rules:
page 12 wrote:
When one or two both (sic) players choose the red side-
* A war is declared. The War will resolve NEXT Round when the Worker moves to the War/Return Space
* Each player who chose the red side is considered an Agressor. (Both players can be Aggressors in a War). Each Aggressor forfeits their War Preparation Cost (0/1/2) Resources according to the Era
* Leave the Worker on the Return/Preparation space. Next round it will move to the War/Return space and the War will resolve
So if you're on the Preparation space, you move in Phase 4 into the War space. Patching occurs in Phase 1, so the result is that you cancel the war that you've already paid to prepare.
