Filters work, but a little differently than before. When opened, they appear to be inactive, but are actually turned on.
You need to turn them off - ban button.
And then gradually turn on the city, or warehouses of individual raw materials or WAREHOUSE
This works for all the goods EXCEPT when you click on only the Required goods button. For whatever reason the filter will then ONLY show RG's for the city that your selected train is currently hauling to, no matter what you do with the city selection tabs.
