Just something I noticed, I had just registered Psychic Miguel in my PokeNav, and I tried calling him - it let me, just fine, even though I was only a few steps from him. Gentleman Hope, who is on another route, however, it wouldn't let me call, because it claimed he was close by. The issue seems to be the locations the PokeNav has them set to. Hope is on Canyon Path, but the PokeNav thinks he's on Light Path. Miguel is on Light Path, but the PokeNav thinks he's in the Ancient Meadow.
Oh, another thing - are there some shiny sprites missing? I just had a shiny Pidove appear, stars and all, but it looks just like a regular Pidove.
Not that it matters, since I have no Pokeballs.
