In the tutorial “Beginner - A game of Margins” I have saved the game about 2 years in. Now after I loaded it again the competition only have one product left and I was sitting solo on every thing else.
The AI started to make the same products again. I did a save again, quitted the game and started it up again. After loading in my new save game the AI was back down to one product again.
I don’t think this is what you hade in mind for the save function
