To be more specific, i interacted with the door that you use to come in, then with the hyperspace hole at the back wall. After i interacted with the space that was either 2 or 3 in front of Giratina, which i believe was where Nyx was standing. Once again, this was my first run through the game, but i transferred a save file from like 1.1.8 onto this computer (6 gyms beaten on that file). I am on the most recent version/patch 1.2.6. I hope this helps out a little bit.
