I collected several diamonds and gunpowder and also had diamond tools of all kinds and put them in a chest. I then saved and quit my game. I came back to my pc, returned to my world to find my entire chest emptied and all of my tools had disappeared. Also my farm animals will get stuck in the corner of my fence and even if I try to hit them, they wont move. When this happens I can try to break a block but it will vanish then reappear again. Also my character will get stuck in trap doors and then will start shaking up and down. I have to then restart my Minecraft launcher in order to fix these problems. These all have happened several times in a short period of time. Please resolve these issues, it is very frustrating having hours of work disappear without warning. And yes I have deleted, uninstalled and reinstalled/ downloaded Minecraft and Java 3 times now. These problems keep occurring. The photo attached is the chest that got emptied after I saved/ quit then returned.
