Namco Bandai has issued a recall notice for copies of Tales of Graces, the Wii Tales RPG released in Japan on December 10. In the announcement, the publisher listed all of the bugs it hopes to address with replacement discs, mostly occurring in "New Game +" replays. Apparently, certain enemies, team conversations, and even key items may not appear in subsequent playthroughs. In addition, bugs in shops can randomly change the types and numbers of items in player possession, and pausing during cutscenes may result in other item glitches.

Namco promises that all of these issues will be addressed in the updated discs, and that players' save files will remain compatible. Users need only send in their discs, and not the whole Wii bundle
Sad thing is, this game had sold some many copies on the first day of release.
