when I got back from playing Minecraft on Xbox all of my stats were reset levels items and pets.

this has happened multiple times on a realm but not to me playing split-screen with my dad his items were reset but when he got on his acc by himself his stats and items were there. this has happened twice in our realm and once in a world but this just happens to me when I got on.

i don't understand why this bug happens and only happens at certain times and only with spilt screen. 

another post from 2019 says the same thing.
