All Missions are unplayable exept “The Signal”, no saved data anymore. Still have achievements and phoenix logs.
Even reinstalled the game again. Didn’t help at all.
Won’t finish campagin until it’s fixed 
I have the same problem pretty sure it happened with the Johnson update for me. I agree it sucked all the joy out of the game for me

Yes man… I stop playing so often because of this… Just awful man, like I don’t understand how this can happen.
I switch from playing everyday to once per week. I choose another main game now. I liked to chill with friends in multiplayer, campaign missions we loved and so far. Not sure if we will get more deletes… That feeling of having more than 100 hours of gameplay all of a sudden reduced to 2 hours. It feels just bad. It is not the biggest deal in the world, but damn! this is so strange man. Cutscenes, skuulllllssss all gone… the logs… forget it! more I think about it, less I wanna know.
Going back waiting e3…
