So I was playing my survival world on the Windows 10 Minecraft edition and I tried to move a chest full of stuff. My inventory was partially filled and when I broke the chest all of the items inside fell to the ground as usual. When I tried to pick them up, they made their usual sound and disappeared entirely. I lost a bunch of things including diamonds, iron, a ton of redstone and many other items to this. I tried reloading the world to see if they were invisible but I found nothing at all.
