Ok I am really confused.
So you put a scanner on your space station, and all it does is warns you about an attack that will inevitably happen within a couple seconds anyways... *scratchs his head*
From what I read on the description of the upgrade, I thought it would basically do what the probe droid does but only to adjacent planets to what ever space station has the upgrade.
Really... what is the point of this upgrade? What does it matter if you know 5 seconds ahead of time that a planet is going to be attacked... it changes nothing nor does it allow you to prepare for it...
