I was playing Minecraft and had to go and do something. I pressed save and quit and waited to return to the screen with all my worlds. I logged out of Minecraft and left my PS4 running. When I got back, my inventory was empty. I lost enchanted armor and tools and a bunch of emeralds. 

P.S. Is there anything I can do to get my stuff back without doing it manually. I don't want to use commands such as /op_restore inventory because I would still like to continue to earn achievements.
