For some reason, the route from the new Shattered Planet (skewer_shattered_planet) to the Lost Beyond is rather difficult to highlight, compared to the other routes in the game.

I think this might technically be a bug with PlanetsLib, because I tried de-converting the new Shattered Planet and Lost Beyond to be standalone bodies around the sun (instead of the current chain from Shattered Planet Approach being the parent to Shattered Planet being the parent to Lost Beyond), and the route was easily highlightable again. I used these values for testing:

PlanetsLib:update({
  {
    type = "planet",
    name = "skewer_shattered_planet",
    orbit = {
        parent = {
            type = "space-location",
            name = "star",
        },
        distance = 82.3,
        orientation = 0.248
    },
  }
})
PlanetsLib:update({
  {
    type = "space-location",
    name = "skewer_lost_beyond",
    orbit = {
        parent = {
            type = "space-location",
            name = "star",
        },
        distance = 92.2,
        orientation = 0.248
    },
  }
})
