Re: Co-op Survival issues and random rank reset?
This seems to be a more common issue with the matchmaking. I believe DICE is aware and are working on the entire matchmaking system.
As far as you seeing yourself as Rank 0, this is just a temporary bug that should go away. I have had the same thing and my rank will show correctly again later. You have all your unlocks, etc, so there is nothing to worry about.
