A POST OFFICE has been opened in Petalburg City. Once per day, you can complete a delivery for the Post Office to earn some extra cash. However, if you don't complete the delivery in the same day, your customers will be unhappy.

Partially addresses an issue in which Multi Battles in the battle tower would enter an infinite loop during their intro. Battle Backgrounds and intro should complete correctly now, but there is still currently an odd visual effect when starting these battles. As this is a known issue now, and is just a cosmetic problem that does not prevent the game from being played, this update is considered safe.
