That's how it is you have to update, if i were you i would backup your TS4 folder whenever you're done playing cos both the game and origin updates can corrupt your Game Saves, there's a Game Saves folder in there but better just backup the whole folder. Make sure to rename it so it doesn't conflict with the real folder. Don't leave it to chance and skip backing up either it only takes once, an Origin update drops and boom... your games gone, so always back up after you close. Unless something really bad happens then you just have to copy and paste the Game Saves into the Game Saves folder should they corrupt or disappear.
