Pokémon X & Y players have reported issues when saving in certain areas of the game's Lumiose City, and Nintendo is preparing a patch for the game.

Nintendo wasn't able to offer a date for when the patch will be available, but it says it will be available soon. In the meantime, Nintendo is recommending that players DO NOT save in the areas highlighted in blue in the map of Lumiose City above.

Nintendo has sold more than four million copies of Pokémon X & Y since its launch. That's a lot of games that will need a patch.

Our Take
Nintendo has a pretty stellar track-record when it comes to releasing bug-free games. It's a testament to their skill when we say that the appearance of this bug is a surprise. Hopefully the patch will be available soon.
