Question for GM

I noticed that Electronics is now using Selenium, but they stopped using Mercury.
Is this by design because Factory Maintenance is using twice as much Mercury?

It would be greatly appreciated if you could post a change log when the output and consumption in corps changes. Thanks,

Agreed. Things like population decline rates due to health is something that was changed under are noses; as well as markets are repeated evident to how products consume and suddenly over produce abundantly.
