This issue is online play only
How it works:
Hosts world will overwrite one of yours if you disconnect from the host, due to network error meaning your internet turning off while playing or you lag. Once you disconnect it will say saving world data and when you go to your game menu you see your friends world where what I believe is your last visited world before connecting to theres ,so be careful ! Also in that world in some chest items they are empty/disappeared ... Which hurts because my world got overwritten bur my friend had my world and he invited to tease me he has my world now then I dissconnected got it back but now all my items are missing . BE CAREFUL EVERYONE
