A situation happened in my vassal league season 9 game vs Paul Heaver last weekend. We were not 100% confident and fast about how to resolve it, but I think we eventually agreed on what should be done. Here's the flowchart:
I used a Starfortress which tried to blow up asteroids left and right, so we navigated through the path that goes to the very bottom of my chart, which can happen when an opened struts vulture starts off in emptiness and lands on a 2nd asteroid.
As I don't want to overly complicate matters, I only include the case where asteroids are involved in this situation.
I'm looking for mistakes and omissions if you can find some.
