[Outdated][Bug 1.04] Multi monitor weirdness

I have a multi-monitor set up. When I click on another monitor the game pauses. That’s no problem, but the weirdness is that when I click back on the game and it restarts, every car advances as if the slots continue producing while paused. Except none of the cars have moved. So it’s like some areas of the game pause(cars on conveyor belts), and some continue(slot production).

Actually pausing the game does not have the same effect.
