Please help me understand trade routes. In this screenshot, why are there no routes to the subsidiary in Placidus? This isn't just a bug in the trade route display; the three trading companies only show two routes each and none of the systems on the way to Placidus have a passing trade route bonus.

It's not clear from the screenshot, but the connection between Rasam and Vyrak is a wormhole, so othe routes are already using wormholes succsesfully. The two pink nodes are colonized by Vodyani arks. I don't know why the one next to Mrigashi is inexplicably unlabled but it is a regular colonized system, and all the other trade routes are going through it fine. The orange node on the routes is a nebula. The route between Vyrak and Jeia is mysteriously showing as blockaded despite there being no ships in either system, but the routes don't claim to be blockaded on the trade screen so I'm not worried about that. I just want to know what my mistake was in thinking I could build a subsidiary in Placidus and get routes to trace there.
