Postgame quest bug? (Spoilers)

[Damien321]

Alright, so I got the Darkrai quest done as far as I'm aware. I did the battle with Shiv, then the freaky thing happened where my game "restarted", then I did the rest of the dialogue. Whenever I received Darkrai however, it's nowhere in my PC or party, and when I try to re-enter the area, nothing happens. Is this a bug or am I just screwing somethin' up?

 

NOTE: I put this in reborn city 'cause for all I know, this really could be just me missing a key detail and not a bug.

This is normal, the quest is not over yet.

Got'cha, thanks a bunch.
