So I am one of the unlucky ones that have lost ALL of my campaign progress, skulls and all of the MP play time etc.
Ske7ch has hinted at the issue possibly being related to a miss match between locally saved data and cloud saved data. Not sure how true this is BUT.
If you delete your local save data and remove your xbox profile from the console. Once this is done, you re-download your profile and launch Halo Wars 2. Halo Wars 2 should download the recent save info from the cloud.
Would this fix the sync issue and return the missing info?
I should point out that in everyones case, the stats on Waypoint are still accurate and up to date, this seems to be just a local issue.
Thoughts?
