I just played a match and i was about to shoot a large planet to its own moon. What happend is the moon continued orbeting the planet that is targeting the moon, making them fly out of the galaxy (and probable a few more) together never having an impact. no way to cancel the move then or to send anything else to it. eventually the game crashed... It was classic pa and the launching planet was much bigger then the moon.
Allas the game does not appear in my replays i think this is because it crashed. Perhaps if you can tell me a way in finding the id i could try to look it up.
