Hello,
I'm currently working on my achievements map and have every achievement (except research, need to farm more aliens for that one) done,
except Mass production 3, which requires 20 million Green Circuits.
I'm currently at 2.8 million after 40h on this map.
I somehow believe that the devs accidentally put one 0 too much in.
There isn't even any use for that many circuits :/

What do you think?

Not a mistake,
Its a hard achievement

Its a milestone achivement. Its not exactly hard, just tedious, or something you get for playing for an excessively long period of time.
