Lumiose City Glitch

I thought that a Generation 6 glitch might make for a good topic, and I found this one. So, apparently, sometimes when you save on the streets of Lumiose City, you will lose your save data and have to restart. A fix for this is pressing the home button for about 5 minutes. Don't know if this works, because I still don't have X or Y, but I'm still planning on getting X this weekend if possible, and then I'll probably make about 50 posts a day.
