• Reproduction steps:

- take a food item that has more hunger value than you can add in one go (e.g. fish fillet with more than -15 hunger), note its weight

- add from that food item to a meal, e.g. take a cooking pot full of water and create a fish stew

- note that the weight of the fish fillet has not changed despite its hunger value being much lower now

 

this can result in silly things like 6 kgs of fish fillet (from a big pike) with only -2 hunger filling up a fridge really quickly.
