So I found what was occurring (what was preventing the ship from moving once much past the solar system edge), and it was this. The belt that carries mats for crushing ice and metallics in the top left was getting jammed up after enough time had passed. No crushing can occur, thus no inputs for fuel ...

Thanks so much for clarifying on the fluroketone and solar panels.

One more question - I have run my first flight and am impressed by how smooth it goes from Nauvis - Aquilo - Solar System Edge... but as soon as it passed the edge and headed for the shattered planet, all the asteroid collectors ...

Hey nice ship, thanks for sharing. Not seeing a way to load up fluroketone into the system in the latest version. Am I missing something?
