I don't know if this happened to anyone else, but my registry just blew up with all sorts of foundable rewards that I didn't know I was due. Ones like Percival Graves, Tom Riddle, Newt Scamander, Unicorn, Triwizard Cup, and Hermione's Time-Turner, to name a few.
I'm not complaining! I just found it peculiar. Hope it was intentional gifts and not a bug.
