f you were playing the new Pokémon X & Y you might be experienced corruption of your savegame in certain parts of the map. If this is your case, don’t panic. Nintendo is aware of the issue and is working around the clock to release a fix soon.
According to Nintendo Life:
Earlier this week we reported on a game breaking bug in Pokémon X & Y that was affecting some gamers in Europe and North America; it was discovered that — occasionally — saving in Lumiose City can cause irreversible corruption of save data, forcing the unfortunate players to start all over again. Nintendo has now acknowledged the issue and advised that it’s working on a fix.
Posted on the company’s Japanese website, the message — allowing for some quirks in translation — suggests that work on a fix is under way for those that have experienced the problem, with a “few days” apparently mentioned though, to be safe, let’s just treat this as a case of “as soon as possible”. The post acknowledges Lumiose City — or Miare City in Japan — as the source of the issue, with advice to save in buildings such as the Pokémon Centre. The map below reportedly shows areas that prompt the bug.
