I need someone to confirm something. As far as I have known so far Cresselia's island has been a random event in ORAS. But tonight I looked out the window and saw the crescent moon, so on a hunch I flew around Hoenn and sure enough found the island with Cresselia on it. Im not sure if I just RNGed it or if its because of the IRL moon but can someone else check? The island is located to the south-eastern corner of the map if you have it.
