Another player's probe is in orbit around the star in one of my systems. I moved some ships to it (although they seem to take up a different position) and attempt to attack the probe. The feedback indicates an attack order has been given, but nothing happens.

What is the expected result here? Are you not able to attack ships that aren't orbiting a planet? If so, the feedback should be changed. If I am allowed to attack this probe, how come nothing is happening?

Thanks.
