I have an underperforming chicken factory, and for some reason one of the processing depts is getting no supply.
Stock is at 0 and utilisation at 2%, even though the overall demand for the factory is outstripping supply
This screenshot shows a dept which is performing ok

This screenshot shows the buggy dept, where its not getting any chicken stock to process

I've uploaded my save game here..

As a sidenote, how come processing depts don't show utilisation as a graphical bar anymore.
I'm sure they used to?
