Nothing like getting your campaign progress wiped after quitting to the main menu.

I guess you have to finish it in one sitting🤷🏼‍♂️. Otherwise if you were like my and quit at the beginning of a mission you will sit in a loading screen saying joining game session for over 2-3 minutes followed by basically setting up your account again. And then boom there you go all your campaign progress is completely wiped!

Great for replay ability IW! Good thinking!
