Platinum question

[Robotsjef]

This glitch happened to me, but not because I synced Sound Shapes. I downloaded and installed two games at the same time (Tales from the Borderlands and Child of Light). I then started playing Borderlands and unlocked a trophy, but the trophy was not a Borderlands trophy but a Child of Light trophy. And I hadn't even started that game! I looked into it and it seems that this glitch happens if you install two games within minutes of each other. Had to delete both games and the borderlands save to fix it. 

 

I think it unlocks a random trophy, guess you have to be pretty lucky (or unlucky ) for it to be a platinum
