I have had Minecraft for a while now and a small thing I have noticed is a glitch for inventory and chests. Sometimes, not often enough to be a problem, when I re-arrange a chest or put stuff from a chest into my inventory it will undo what I did after I close the chest. It would only do it once when it happened but the last time I had to go back to my chest about eight times, which was really annoying. The end result of that last time was my house and inventory completely burned because a bed turned into a bucket of lava that I had moved into a chest.
Chest Glitch?
