Thanks for playing and the feedback!
The max route length leads to a poor experience and will be removed.
Hmm I will try to reproduce you issue with the route not spawning... Maybe it was invalid and red so difficult for you to see? Either way I will investigate!
The initial spawn has a trade station that accept scrap and ore. Scrap being a supply good on almost all nearby planets and ored being an unlock but is present on all of the rocky planets.
But the discovery of these is a poor experience and one that I aim to improve.
Thanks 👍
