Me and my friend have decided to get down in the LASO playlists. We started playing Halo 4 LASO and got to mission 3. Once we opened to resume the playlist, it was reset back to mission 1. We really do not want to do it all over again as it took hours to accomplish already. If there's any advice or fix on this please assist. This isnt the only playlist it's doing it to and it's making me not even want to play it anymore. Thank you!
