that might be a glitch with your system. some well loved old advance games that were played often can be a little touchy, make sure not to bump the cartridge while saving or transfering data- wierd things can occur, both good and bad. my Ruby version gave me a shiny gulpin when i was transferring the pokemon. my adorably annoying cat knocked the DS out of my hand when i was transfering the 6 pokemon to my diamond pal park.
