I just have had a nice race with another civs colony ship. We headed for a system with a pq5 and a px19 planet. Unfortunately the AI arrived first, but because the PQ5 planet was one smal square (parsec?)near, the Torians colonied this world and I could still get the pq19.
This is not just about the Torians, any civilization do this. Btw, I also run a lot of times into system where low class planets are already colonized, but high class planets are not. Sometimes when a system have 4 low and 1 high class planets, I see the AI colonizing one low quality planet after another, geting the high class last.
Thats just stupid. A fix would be great.
