Description of Problem:
Updated my technic launcher today at about 10:00 p.m. central time and once I logged into technic (single player) my entire save had reverted to nothing. All progress was lost, almost all items dissapeared, even the village I was next to was reduced to nothing, including the villagers. Just want to know how ti revert to an old back-up of technic, or even recover my old save, because I included the save of my worlds in the back-up.
