When playing Minecraft on split screen with other people, the majority of the time players who rejoin the game will lose all of their data (inventory, position, experience, skin, etc). Only the host of the game will have their data saved. The players are not on guest accounts, they are signed in with different Xbox profiles.
Having the same problem as mentioned here, but it is not resolved on the current version.
