i play with my friend split screen on our survival world, my character always loads fine, but my friends (or the second player) has two characters the game for some reason alternates between.

what i mean is, one day she will log on, and have iron armour and xxyz in her inventory. then another day when we play, she will have no amour, and something else in her inventory - and spawn in a different location (the last place she was, when she last played as that character)

it seems to be working exactly as if she had a different xbox account and was logging in with that account, however, i know thats not the case, because there are only two profiles on my xbox, and we are careful to make sure she doesnt sign in as a guest. its just random swapping between her two players.
