Loading up Factorio today, after a few days absence.
I was greeted by the sight of hundreds and hundreds of construction robots zipping around. I could not remember what task I had set them to last I played, but it must have been important. Not wanting to disturb, and too embarrassed to go check on their work to see what it was, I ran around the base trying to look busy while they completed their tasks.
They must have figured out I was faking it - that I was just running around in confusion and wasting CPU cycles that they could put to infinitely better use - because shortly after, they kicked me out by making the game crash.
