I have a steam installation of Factorio 0.16 and an experimental version 0.17 in a folder somewhere else with a bunch of new saves to test the new features.
I'd like to do the "Mass production 3" achievement on steam and if I get this right, this achievement is save-independant. Once the 0.17 gets stable and downloaded via steam, I'll merge the 0.17 new worlds I tried with my current steam installation.
Question : when the saves will be incorporated in my steam installation, will the total electronic circuits add up to the score?
And more general, where is the green circuit counter stored?
Quick edit: I tested the update of the green circuit counter during a session, the steam achievement counter is updated after the game exists. The ingame counter is not precise enough (rounds to first decimal in engineer notation)
