Also, currently the pathfinding system prioritizes paths on your current constellation instead of the actual shortest path when it comes to Interstellar highway travels. I think.
One example of this:
When I travel to star system A: this is the route it took.
However, when I travel to star system B, it jumped straight to star system A, then goes to B with a shorter amount of fuel spent.
So why did the system not jump straight to A when I wanted to go there (it’s clearly possible to via Interstellar - proven via going to B), yet took the longer route?
