says: I left my Minecraft world and when I came back a day later to play my whole inventory was empty and I was at spawn. The thing is I didn't die so i don't know why. I made new stuff to make up for my old ones. Even my enderchest was empty. I was confused. I filled up my enderchest again and when I logged off and came back I had my old stuff back. The materials I used for my new stuff were still gone
