I startes up bf4 on my ps4 and clicked resume on the camapaign but it restarted it completely, I don’t know what to do and I was a good 5 hours into the game
Same thing happened to me. Sadly the only option was to start from the beginning again. Tried restarting my console, my router…nothing. Sorry pal.
Shit man this fucking sucks… I restarted, I guess I’ll have to speed play through it 
I ended up doing the first level three fucking times :-/
Yes this is a known issue. The save file becomes corrupted and is overwritten when you start the game again.
Happened to me a few times. Today even.
Try beating the game,making one if 3 choices (that unlock weapons I might add) leaving the game, go back to the game 30 minutes later to do the other two endings and found out everything was lost… Dice… Fuck you
I’ve done the first level like 15 times. I just gave up.
Me too. Fuck it. Multilayer is good enough
Progress on that also deletes though
Man this has happen to me 3 times n everytime I lpse my save progress, they put out a patch that apparently fixed this but not for me, I finally gave up kn campaign which was a shame cuz its decently entertaining
Not for me…my mp progress has saved since release day. Weird
