First press the windows key

Second, in the search bar type ‘run’ and open the application.


Third in the blank space type this command
%USERPROFILE%\Documents\My Games\South Park - The Stick of Truth\save

Fourth, this command will take you to the save game location, copy the entire folder.
Fifth look for the local game files (you can do this via Steam) once inside paste the folder.


This should be enough to fix the save bus and recover your lost games, let me know if it worked for you or should I explain better how to do it, it worked for me, I hope it works for you too.
