If you play Pokémon X and Y, you may want to know that saving in certain areas in Lumiose City will corrupt your game. The map below shows where you shouldn’t save.
If you have saved your game in one of those highlighted areas though, there may be a possible fix. This Reddit Forum Post states that you may be able to recover you game if you follow the following steps:
Step 1: Load your game.
Step 2: As the game loads wait for the music to start.
Step 3: Mash the home button until it works.
Worked for me after about 5 minutes.
Nintendo have also stated that saving in a building (or a Pokémon Centre, for that matter) will not corrupt the save. They have also stated that they are working on a fix, but no time was given for the release date of the fix.
Remember to the share the word with everyone you know who is playing the game!
I sure hope this doesn’t affect what happens when I play the game…
