So before I found this wiki I aborted a couple Free World missions. Am I able to go back to them or continue somehow or they forever lost?

I think it was the rat pack pirates and finding the republic drone

I have been trying to accesss my savefile so I can modify it, but all the guides are for a windows based installation. Can anyone help me with this?

Hey guys, i have been playing endless sky for over a year now and got quite a few saves, and now buying a new laptop. The thing is before i was palying on an old macbook, and now i'm getting myself a windows operated computer, and i don't know if/how can i move all of my saves from macOS to windows?

I can't sell Premium Materials. Therefore, after 'SELLing ALL' my cargo, the SELL ALL button is still active--it doesn't switch to the SELL OUTFITS which is inconvenient for me since I make money by raiding enemy ships.

Also, as you can see, the UI isn't big enough for an extra commodity; it pushes the Cargo Counters out of the way.

The Premium Materials also seem to disappear with no observable pattern (at least none that I have observed). Some ships also have premium materials in their cargo holds (as seen from scanning and boarding).

I didn't notice any mention of this in the ChangeLogs (I just searched for 'Premium Materials' in the document). So, I am stuck.

It doesn't ruin gameplay of anything. It's just a minor inconvenience.
