I beat the campaign and tried to go back to playout the rest of whatever I had missed. Little did I know, the game would freeze at the title screen after the credits when I tries to hit continue. Oddly enough the title music still plays. Went to load a  previous game instead to try to load up various recent saves but still nothing.. I clicked the new game tab and it pops up! Confused by this. Any answers out there?

I have the same problem on my ps4 version. I don't have an internet connection and I can't download patches.
