Glitch

So on my survival world I was mining and came across some iron horse armor. Then, as I kept going it disappeared! I went back and looked everywhere but it was gone. The same thing happened to multiple items, including an enchanted fishing rod. This glitch is VERY annoying, as I am now missing my items. Other than that, the game is great.
