So I was playing on my Minecraft world and noticed that a big chunk was missing, I had thought it was lag so I reloaded my game. I come log back into the game and it is still there. I have cheats enabled on the world so I tried to fill it back in. But it had glitched into part of my storage area and I lost about 10 chest full of things. I am not sure if this is only a problem for me or anyone else.
