My LASO playlist reset after the recent 70GB.

I recently updated my halo MCC and I have noticed that my LASO playlist had reset and none of my progress was there, has this happened to anyone else? And if so can you please help me?

Yeah it’s cooked. It’s says I’ve completed a few missions yet puts me back to the first. Simple fix would be to allow us to start from any mission of a playlist and then go from there. Don’t think there is any fix

Looks like the saves are incompatible with the latest update. You MAYBE could uninstall the latest version of the game and install it from the disk offline (assuming you got the disk), then try playing it with the offline version?
