Was playing Cursed halo with a friend and we got to the part in the campaign where "Mom said it's my turn on the Xbox" My friend kept saying his game was frozen and I was telling him his character was still moving. We eventually came to the realization that we were de-synced because of the cutscene. This probably should be pinned until it's patched in case anyone wants to play with their friend(s) so they don't get too disappointed. What I think is odd is that multiplayer (Slayer, CTF, KOTH) works fine.
