Yes, it is in the stable version, and it just now did the same thing with a cargo run, and yes it is in the stable version. Then I spent quite some time trying to find the files in question, then finally get the brilliant idea to make invisible files visible... Since there's no way to file share here I'm going to see if I can manage to remember my user name and password for github correctly and send you the files that way. EDIT: Unable to send the files themselves, I'll copy & paste the technical information down below though.
Also, I ran an undead ship for a moment and noticed that the UI insists that having "low" food and water is bad (haven't played the drones so I don't know what it will think about that).
