Hello, I noticed a mistake.
The problem concerns assemblers, and correctly the cooperation deselecting option. I have this cat once and it is not there again.
Button for cooperation mode is in “production” panel in upper right corner
Did you found that button?
the button is not there. I am here where I have this window
you see it is downstairs now
From my observations, this option is available every 4 hours. There is no sound after restart. and so every 4h
