I haven't played my soulsilver in a few months, and when I opened it, I found out that my typhlosion had lost two levels, and my giratina seemed also to have this predicament.
I distinctly remember a guy giving me his giratina at level 81, but after two years it's at level
85. I don't battle that much, but after using as my primary sweeper ever since I obtained it,
It's minuscule gains somewhat startle me.
