It seems like the mass discussion started two days ago, but over at 2ch and other Japanese forums and boards there's been a serious glitch going through all the people who currently own Japanese Versions of Pokemon HG and SS, and that applies to all the Japanese releases, I'm posting this info for those who did import the HG/SS version, and of course, if this is a software related problem, those people who downloaded it.
The details of the glitch is not clear, nor is the conditions of the glitch occurring clear (One thing for sure is it's not time related, people at 2ch have reported the glitch occurring at game times of 60hrs-200hrs, or so they say.), but in a nutshell, the glitch makes your save vanish, just like the good ol' Generation I-III versions. Again, it's not confirmed whether it's a hardware or software problem.
Whether this glitch is real or not is well, unconfirmed, there is a chance this is a big, big load of BS, but it's always good to be careful about it, especially after HG/SS has two confirmed glitches (Folding up DS screen into sleep mode sometimes, and going up a ladder in the Twin Islands from its back leading up to Articuno can both crash the DS into black screens.) and a buttload of smaller ones.
