This problem is so frustrating!
If it helps, please note that I play on the Xbox One. I remember one day that I was looking through the high-level LMG's for multiplayer, since my primary weapon of choice at the time was the LSAT. I got to the infamous M249 SAW, looked at the challenge I had to complete to do it, only to see that I had to seemingly beat the single player campaign and "make the final choice." I decided that I was going to stop with multiplayer for a day or two to beat the story. I got to the mission where you break out of prison with a russian. After the opening cutscene started, I decided that I was tired enough to lay down and go to bed. I woke up the next morning, pressed the Single Player button on the main menu, but instead of being greeted with the "continue from last checkpoint" option, it told me to select a difficulty level for my new game. Since then, I have played through the game, getting progressively farther and farther, but every single time I stop to play something or do something else, I cannot continue. I have to start again from the veeeeeeerrrrrryyyyyy beginning. It is to the point that I actually broke my XBOX One Stereo Headphones in a fit of rage (nothing a few zip ties and some good old fashioned inginuity couldn't fix). DICE, you really need to fix this, regardless of how far Hardline is into development.
