new update - game now broken?

I told the game to download the new update after it found it when trying to launch it today (I use energy saving mode on the console so it isn’t automatic). Now my MCC (digital copy) is stuck at 40% - Ready to Start. When booted, trying to do matchmaking shows Halo 2A at 62.5%.

Nothing is happening or updating in or out of the game. Rebooted. Nothing.

Thanks 343i, your legacy continues.

I was in the middle of playing Halo 4 when it updated and it sent me back to the beginning of the level.
