Whenever I want to change my settings or turn on mods, I then restart the game to have the mods loaded. After the game starts, nothing is saved and the game acts af if I turned it on the first time. I reinstalled it so I got all the welcome messages on the first launch which re-appear when I restart the game and as I said, no settings are saved and all mods (even the built in ones) are disabled automatically.
I would be grateful for any solution to this.
