I am not sure whether this is a bug or a feature, but if I try to get the best colony I just send out waves of colonization ships in this hope to get a best planet.
I noticed in my list there are two waves containing an "?" at the target coordinates. Now I don't understand why this is the case, because all target spots are empty.
Below my current attempt to get the biggest planet possible on a location 3. The coordinates are very close to each other (for example, waves flying to 2:200:3, 2:202:3, 2:204:3 etc)
So why these question marks here?
