loss of campaign progress

With the new year approaching, and another Halo on the horizon I am wondering will we ever see a fix for the loss of campaign progress issue that so many of us have experienced? And 343i saying that they could not reproduce the issue is just proposterous. I love the game i am just wondering why this issue has not been addressed.

I can reproduce this issue for them whenever they want. It just wiped everything I’ve done, and refuses to save new levels that I beat now. It happened to my brother yesterday and he lost the 1st 2 missions, I just lost the first 6.
This game is garbage.

This game is far from being garbage. Althoough, I wish that they would update the issues it has.
