I've always loved the idea of every trade port gaining a little bit [0.1 or 0.3 or something] for every phase jump or planet in the longest single trade route.

What I find odd is how sometimes this longest trade route line is gimped, in the sense that it will miss out planets with trade ports/SB trade ports instead of making an awesomly long link. For example I've had situations where you get a spiral of planets and jumps, the longest trade route could go all the way around and be like 20 jumps long but instead it takes a retardedly short 4 or 5 to the centre. I have no idea why it does that despite having every planet with trade ports/SB ports D:

Would just like to know what I can do, because if it was user defined where you could create the longest trade route via clicking from trade port to trade port, knowing no planet can be used twice I would have some awesome trade routes c..c

Here is a recent example, all the planets on the left side have trade ports or SB ports, but why does the longest trade route line stop just there ? Is there something I am doing wrong ? D:
