The current version can handle all bulk materials (BULK) and liquids (LIQUID) defined on the map or in mods.
The prices are 10% more than usual. Ideal to keep the productions running when the own grain is running low.

Buying grain is common in agriculture and herewith a bit more realistic than buying in production.
Who does not play on heavy should then also this mod of me times look at: https://forbidden-mods.de/filebase/file/31599-einkaufspreisanpassung-an-schwierigkeitsgrad/
When you are useing Revamp, this is already integrated there.

If you don't like it, you don't have to use it ;)
