Flour?

[harflimon]

You've said you milled flour at your "Home" and "chest", just to make sure are you using a windmill when attempting to mill flour? Because you have to be using a windmill to mill flour, it won't do anything otherwise. Not sure why it would disappear on you if you aren't, should just pop-up red text telling you to use a windmill. Are you sure you weren't just "threshing"? Also if it's tier 1 cereal it gives "oatmeal" which is a type of flour, I know that confused me at first.
