This is nothing to LOL about!
I remember that the old pokemon games used to delete your saves if you started a new game, even if you didn't save. I challenged my brother on that, and ended up deleting our Mew save. That sucked.
And that time I caught missingno. Supposedly, it can't delete your save, but...my save got lost somehow. That sucked.
And that time...or two...or three...that I my game died during a save and corrupted my save. That sucked.
I played RBY over so many times I can't even count. Loved it every time, but still...losing your save is never fun, unless it's intentional :/
