Or Reporter might be wrong, maybe.
I actually decided to use SS instead of Platinum because of the NPC issue in DPPt. I got the egg in SS with everything set and traded it to HG, I ended up with that result. I still can't figure out why the Manaphy has some wrong IVs and isn't shiny. Is it possible that I was off by a frame or two and it resulted in this?
