Saving

My multiplayer is saving however my Campaign isn't saving. Through trial and error, I have found that if you play campaign and not multiplayer the campaign save will still be there once you exit the game and reload it  but as soon as you play multiplayer and turn off your console (I have a super slim ps3 500gb) the save won't be there. I loaded up my playstation plus save and when I loaded BF4 my campaign file was there but of an older save.  

Semi permanent Workaround☹️once you play multiplayer after finishing the campaign, the only items you'll keep is the shank and the machete)

Start playing SP campaign and don't play multiplayer until you have finished the campaign. When I did this, the save stayed there as long as I didn't play multiplayer. Although next time you load BF4 the campaign save will have been wiped, you do keep the shank and the machete. If you don't care about the shank and machete, then there is no point playing it until EA come up with a patch, but if you do, then have fun.
