So I started making beverages out of coffee and noticed that everytime I quit the game and come back in the fatigue reducing stat goes back to 50 and the beverages get even more fatigue reducing effects but the coffee uses remain the same.
For example: I make a coffee beverage and the beverage has -5 fatigue and the coffee has -45 fatigue then I quit the game and come back in the coffee now has -50 fatigue and the next beverage has -10 fatigue. Then on the 5th beverage the coffee disappears and the mug has a -49 fatigue effect.
