So there has been a glitch in the new pokemon games that even though I haven't run into it, thankfully, I think people should be aware of. It apparently involves saving around one of the cabs or other various spots in Lumiose City when you're outside. I would look into the details for this which you can find here ---> http://playeressence.com/beware-gam.....h-pokemon-x-y/ <--- Be safe fellow trainers
