It's a mess, all of the production chains are now broken. I can compensate for some by turning buildings off but it's not possible to balance everything that way - Example, I can turn 3 of my 6 bronze weaponsmiths off but I have 15 copper smelters and turning 8 off means that I don't produce enough bronze while only turning 7 off means I run out of copper and coal. Either make it work like a buff (add to output only) or stop it entirely. As it stands my production during 'production week' is actually lower than normal because I have to turn so much off to make things balance again.
