Battlefield 4: Single Player Campaign Progress Not Saving (2020)
So I reinstalled bf4 on my Xbox one after years of not playing it. After playing multiplayer,I decided to try the campaign again since I never finished it because you know. Anyways I got pretty far into it and then got out to play some rocket league. When I went back to play it lost my progression... Again. It's there still no fix? I reset my console and still nothing. Also BF3 was so much more fun.
It's been happening to me too (PS4).
What i was doing after i finish playing the story i backup my save file and i upload it after i want to play.
I don't know its happening to other people.
