A friend and I were playing the Halo: CE LASO playlist. We got to The Library and were stuck on it for 3 1/2 hours. I decided to leave and do The Library on my own and I managed to beat it in 30 minutes. We started Two Betrayals afterwards because I was going to recover his account and beat TL for him later. We didn’t play long because we knew it would take long and were tired. I recovered his account later, went to the Playlist and it realized it doesn’t start him at The Library. It skipped TL, and put him directly on Two Betrayals. I can’t go back and choose The Library so I can do it for him quickly. Does anyone have any idea what is going on?
EDIT: Also, my friend instantly crashes when he loads the Halo 2 LASO playlist.
