I think there are a couple issues here. The first is that the price for Maris Otter is not passing through correctly. In my inventory, I have it at $2/lb. I tried adding a new entry but for some reason the price would not save no matter what I did. As always, there is a high chance I'm doing something wrong, but i tried removing the grain from the recipe, saving, updating the inventory, going back into the recipe... Let me know if you need more info!
