Hey so this is kind of an annoying issue.
I have 2 save slots my game (slot 1) and my friends game (slot 3) we are both playing the game VERY differently and I always put the saves as far away from eachother as i can after a few bad Final Fantasy moments when I was a kid. So now I downloaded ep 5 and noticed in the "previously on walking dead" that my choices were off and the beginning of the ep many characters i saved were dead. I reloaded it a few times and noticed the same and eventually said screw it and just tried to replay ep 4 and make the same choices, and now ep 4 wont play. All I see is a blank screen and hear forest noises.
I tried your "copy the data to slot 3" solution but obviously do not want to overwrite my friends game so i did it with slot 2 and it wont work, so now I seem to have lost all my ep 4 data and cannot replay it. Either somehow recovering the data or just allowing me to play ep 4 will help.
ps game is awesome and I really want to see how my choices play out
