Hi,
I saw a bug with the food values (hunger, calories, etc) when u are canning food.
For example when u jar some cabbage i tested letting one untouched, another i ate 1/2 and another I ate 3/4 of cabbage, Jar them, open the jarred cabbages and puf!, u have 3 full cabbages again. it remember the bread bug (and similars like water melon/ Ham) when u use partially ate items.
It seems it returns another diferent item when u use the open recipes and jarring recipes.
