My BF4 Campaign progress was reset too. At first i was confused. I was in a party with my friend. and He had no trouble starting his campaign up. I had just spent 3 Hours getting through probably 13% of the campaign.... Now I am kinda mad to know it happens to others as well. My brother told me how DICE and EA rushed through BF 4 to get things done and i assumed that was false but with all the bugs in it I cant deny it anymore. Once i was climbing a ladder in campaign **SPOILER DO NOT READ IF YOU HAVE NOT GETTEN PAST CAMPAIGN MISSION WITH THE US TITAN** and after what's his name dies i got the item and headed up the ladder, then I flew off and landed somewhere on a helipad and died... Not even joking.
