No it is not fixed and the last patch was a joke. Still no ranks, so matchmaking sucks, still games where teams are uneven. Still many bugs in mulyiplayer. BTB still has big issues finding games. Want to play with a party/friends? Good luck. I would highly recommend not to buy a Xbox One for MCC. No idea when this game will be fixed. It has been over 2 months and tons of patches, and it is still in a unacceptable state for Halo.
