Data gone from Master Chief collection

Games Halo: The Master Chief Collection

Hi,

I don’t know if this is caused by the update or not but all my setting have reverted to default plus customisation and a few of the maps are saying I’ve not completed them even though I have, Like all spartan Ops maps say not done any of them even though got most of the achievements. Any idea how this happens as my campaign saves are still there just not the rest.

Thank you.

Same thing here, all my campaign stats are gone, and i refuse going through the trouble of playing Halo 2 on Legendary so soon.
