Food/small coin exploit

I noticed when cooking some deer meat i hunted so i could sell it ( if u dont know cooked meat isnt counted as stolen)
I started with 200 deer meat and 2 deer kidneys as i cooked the meat and just before the screen went black i clicked it again which brought up the cooking menu again and i selected the deer kidneys the cooking scene ended as usal but when i sold the meat i noticed i had 200 kidneys and 2 deer meat

Deer meat in the inventory is worth 13 but kidneys are worth 50
I can sell them for around 17
This may not be worth much to some because it is hard to find people who want to and have enough to buy it but its still some quick coin and may be able to be used elsewhere for example hunting quests where u look for liver, u only need one liver and can use the meat to make 100

Worth mentioning early game i hunted alot of deer and sold the meat. mainly in rattay where a few vendors buy meat e.g. traders, butchers, grocery and bakery… just a few trips i made 10k early game
