I realize that there are already several topics about save issues, and that is has been plaguing the game since the second episode, but this is goddamn ridiculous and I haven't seen a topic about it here on Giantbomb.
Basically, at a (seemingly) random point in Episode 4 when the game is attempting to save you will get a error message that says that the save has been corrupted, and it will try to recreate the save. The game will then freeze, forcing you to shut down your console. Once you restart the console, all of your saved games, even the ones that weren't in use at the time, will be lost
So this just happened to me. I finished Episode 4 yesterday, and today my brother was working through his version of the game, when he suddenly got the error message. Now we have lost two full games, and the patch that is supposed to fix this isn't even out in Europe yet. Even with the patch is seems almost certain that our saved games are lost. What is Telltales response? Start a new game at Episode 4, with random choices.
I find that unacceptable, for obvious reasons.
