Actually Additions does not work with Spice of Life rules and diminishing returns. After speaking with the dev of Spice of Life this can v fixed by looking here. https://github.com/squeek502/AppleCore/wiki/Integrating-food-items-with-AppleCore

R105 specifically

Oddly I think all other AA food follows Spice of Life fine. The coffee is odd. As you drink it you can see the nutrition % go down but the actual food value never changes.

Guess it would help mentioning I'm using the 1.10.2 version.

I do everything the way it is listed on that page.
What exactly is the problem with this?

I will do a bit more testing and verify this works as it should once more.

Seems like this works fine to me.
