I was playing zombies last night with 3 of my friends and the game froze for all of us at the same time at level 15 when I put my Titan in the pack a punch. My KN57 was already Pack-A-Punched. No error code the game just looked like it paused for all of us so we quit. Now when I came back on today all my zombie progress is gone. Can't customize any weapons (all level 1) or pick any of the starting weapons.
Also everytime I start the game the graphical settings are back to default. This did not happen in the beta.
Playing on PC.
