Many buildings are returning, but as you can see the categories of "Farm", "Mine", "Refinery", and "Factory" have been extended to be a bit more specific to what types of products can be made. (It didn't make much sense that the same building you are extruding iron rods is the same building you are pasteurizing milk, brewing beer, and mixing metal alloys.)

I've already gone through and changed every item to their new building, so I am well on my way to getting the game playable again!
