Seems like my destiny with saving would be a bitter one.

My God Eater save data was corrupted for unknown reasons ( I backed it up on my PC ) , my The Witcher save data was corrupted ( ... Game crashed half-way through the saving progress... ) and oh yes , my Disgaea save data is corrupted yet again.

Did I mention I've lost all my FFVII , VIII and IX save datas as well?

.... We need a new saving system!
