A bug which occurs to only cooked chicken & all types of consumables that once consumed, changes to its empty item state (such as potions and stews).
I've been testing gameplay and play around with the latest beta to eradicate as many in-world bugs as i could possibly find (not including game crashing bugs because those occur very randomly and the game has been in this condition for a very long time)
(And also there's another bug with the "map" item flickering when it's hold, both in hotbar and off hand which i'll give another ticket for)
Thank you for your report!
