At long last I have tried my hand at mining...after collecting and refining 100% of Rutile, I hasitly flew off to sell it...however I noticed that it didn't register as cargo? Am I missing something or do I need to undertake further actions to make it available for sell? As it was I ended up pressing the vent button by mistake and ejecting it all over the space station floor! Nice, no way of collecting it back up again either seemingly?
