I'm in the goldenleaf auditorium and I can't get out. I've tried multiple times but nothing happens. Also does anyone know where I can find ditto in Goldenleaf town? Before I got stuck I looked for him everywhere and still couldn't find him. He wasn't on the Giratina statue. And is anyone else having a problem getting into Gearen City? Whether I use the truck or the train, I get the same result everytime. Some random text pops up on my screen before my avatar starts walking on its own for a few steps until it just stops and then I can't move at all.
