I remember buying fallout 4 and when the dlc came out I bought those digitally. My PS4 died so I bought another, linked my accounts etc.. two years later I decided I wanted to play fallout again, so I load it up and go to download the dlc and it's asking me to purchase them again. I check my library and they're gone. I check my game and the files won't load because I'm missing the dlc files.

Anyways I contacted PlayStation who said that because they have no record of me owning these on their end they can't help. I have even the purchase emails but because they lost all the data on their end they refuse to give me my money or dlc. So yeah that's when I realized that a digital library can just be pulled out from under you, no matter how much you spent on it.
