UPDATE #2: The promised fix has now been released in Nintendo eShop! This version 1.1 patch will fix both the Lumiose City glitch and one with the GTS, which would come up with an error if you used any of the search filters. If for some reason you can't find the patch for your game in the eShop, scanning these QR codes should solve that problem.
They have also released a map of where the save glitch is most likely to occur, with the problem areas being highlighted in blue. If ever in doubt, save inside a building, or just don't save in Lumiose until the fix is released.
For those who have not read about it already, there is a GLITCH in Pokémon X/Y regarding saving the game in Lumiose City. This glitch WILL corrupt your save file, basically rendering it unplayable!
HOWEVER! There are ways to fix the problems this glitch causes! They, as well as the glitch itself, are detailed in this video.
Additionally, it appears that people are able to save inside the city's buildings without any ill effects, which is also good.
In case any of you cannot access Youtube for whatever reason, the article on the glitch can be found here. And just comment or note me if you're in the "can't Youtube" boat and need to know about those fixes.
Lastly, please tell everyone you know about this glitch and how to deal with it, and make sure to share the video and article. If we raise awareness, hopefully Nintendo will release a much more permanent fix to this glitch!
P.S. If you have any additional info on the glitch or another way of fixing its effects, please comment either here or on the linked video (or both if you can).
