So, the infamous Luminose City save glitch affected quite a few people, but Nintendo has now officially released a patch that you can download now on the 3DS eShop! Once you’ve successfully downloaded it, you’ll see a small Version 1.1 on the title screen of your game, which’ll indicate that you shouldn’t have anymore issues in terms of saving outside of buildings in Luminose City!
For those of you who missed the fiasco, Pokemon X/Y had a bit of a game breaking bug randomly when players would try to save outside of a building in Luminose City. This pretty much applied to the outer rim of the city, but there were a few isolated spots within the city as well. The bug would cause games to crash, and although there was technically a temporary fix found by some of the players, a patch is still the best way to go.
