the ai seem to be able to to this granted its most likely just because well its the ai, but still when i set my scouts to auto explore they all end up getting killed because they all keep going back to the pirate base instead of exploring unknown planets, or you keep losing your trade ships because they have decided going through this very deffended enemy planet is faster then going around, so my thought was, why cant we select a planet so the auto programing of flights (what ever the technical term is for it) refuses to let ships go to that planet, ive also noticed some times the ai seems to have control over there trade ships as a couple of them just sat there going around my planets (i didnt have an old trade aggreement with them and they werent orgianlly there planets)
