It is in some cases possible to shorten the amount of hops in the longest trade route, by building a trade port on a planet that links two other planets. If those planet were separated by a longer chain of planets before building the new trade port, the longest route shown in the map is shortened after that. Will the trade income from all trade ports drop in such a situation?

I forgot to mention that I am playing mostly against hard AI. And yes, it is very easy to overpower the AI just by capturing all the neutral extractors and dominating the black market. Of course, overpowering the AI is very easy for any skilled player, but I think that making the AI care a bit more about neutral zone extractors would require much more effort from the player.
It seems like the AI is completely ignoring my captured extractors on neutral areas, and just let's me use them for the rest of the game. Also at least in my latest game, it did not care to capture the extractors next to it starting planet in three hours. This really makes the games too easy, at least on some maps. I don't think the correct behaviour would require any arcane AI coding skills, and would have thought a search had found many topics on this issue, but found none. I might have missed
I also noticed the same inability to move the camera in certain planets, while playing a multiplayer game. I could move the camera to the center of the planet by pressing space while it was selected, even though manually scrolling to that point was impossible for some reason. After that, though, the camera was beyond the previously mentioned boundary, and I could only move it backwards to the zone it was restricted in.
