I had this problem on PC. What i did was go into the orgin client, moused over battlefield 4, and clicked on the little (i) button to take me into settings. I turned off cloud data so it used my local settings, restarted orgin and My campaign was back to normal after that. Aparently it never saved my campaign progress to the could, so when i told it to load from cloud, it loaded nothing but a new campaign. If it's using local data, it will have to be on the same computer you played the campaign on to load your progress. Hope this helps somewhat.
