Question: I just got the latest patch and the next time I played the game a message appeared saying that there was a problem with the game data and a re-installation is necessary. Everything is working but is this normal?
Answer: On PS3, game data is installed to the console the first time you play the game, or after recently clearing game data. When a new patch is available, the download of the patch may interrupt the normal installation of game data and then the next time you start the game the game will prompt you to re-install.
This is normal and not a cause for concern.
