When I leave my friend's world on minecraft, my inventory doesn't save and I'm at spawn point again, basically as if I'm a new player. 

i join using LAN, and I play on the Xbox 1 and he plays on a windows laptop 

ive seen this bug being reported before, and for some reason, it's been marked as resolved even though this is still an issue that hasn't been resolved at all. Please fix this because I'm tired of just remaking all my stuff every time / putting all my stuff in chests before I leave the game.
