In the current version (0.26) , I can't craft Carbon, since the only available Combustible, "Organic", is already selected (as it is the first ingredient and you can't select the same item for two different ingredient slots even if it qualifies for both and you have enough).
Also, the game keeps re-enabling Autosave after I turn it off, the title screen defaults to "New Game" even when there is a save file (most games default to Continue when there is a save file).
