Heres a annoying glitch I found on mari0
When I make a map and on the last level of the map pack (like a world 5-3) I put bowser and a bridge with the hammer you use to kill bowser then this happens. "thank you mario but the prinseces is in another castle" the hell? So I found out it must be on the last world and it has a chart (like 4444) and you need to select the third 4 on the chart. Bowser will now throw hammers when you kill him you actually rescues the prinseces.
