I'm stuck at the GDC Tournament arc. I was supposed to go into the black ship, but instead I flew to Sashila Village because I realized I forgot to do some sidequests, but now that I've completed them, I cant return to the Tournament area! I can't fly back, the train won't let me go anywhere except for route 9, and anyway to walk into Grand Dream City is blocked due to story. Is there anyway in or did I goof up?
