In my first attempt to play Space Abyss I easily manufactured an Thiol Extractor with a skill of a few hundred of manufacturing, before abandoning the game because my pod had vanished...
In my current game I have already raised my manufacturing skill to 1000+ and still failed constantly to produce a Thiol Extractor - without which I can not produce "refined Therite" and are thus barred form manufacturing a shipyard and producing any better spaceship...
