Hey so I've just beaten Adam and watched the Grand Dream Ball scenes, talked to Ren & co., and then flew out of the Tournament Stadium outside area to do some sidequests, but I seem to be unable to re-enter the Tournament Stadium to continue the game, I can't enter GDC (I think this is meant to be the case but I'll mention it anyway) and I can't catch the train from route 9; the destinations are Grand Dream Station (which says unavaliable, presumably because the city is closed) or Route 9 (and it just does the black screen transition and leaves me at the Route 9 station). Send help, thanks.
