Minor map changes in 8-4

[p]This time, the item became newly obtainable from Legacy, but since it didn't appear at all in 8-4, I placed the Moon Orb at the final position on a certain floor where the Tier resides.[/p][p](It was placed purely as a decorative item/souvenir, not intended to affect scores. If your score increased, we apologize. Or maybe... congratulations?)[/p]
