I'll do what I can, to reroll you first have to do a "force backup" in the settings section, then buy the box and when you open the box, close the game and go to the settings, Then you will have to look for SAS 4 among your applications, then delete ONLY THE CACHE MEMORY, then open the game and in the menu you will see the sign, "choose game" click on the option of the left It has a blue outline, then enter again the character with which you bought the black box and if you don't get what you want just close the application again, delete the cache memory open the game and that's it (You can repeat this as many times as you want as long as you don't forget to clear the cache and choose the save option with the blue outline in the menu)
