A bug has been found in Super Mario RPG for Nintendo Switch which may cause you to become unable to progress in the game.
In some cases, after the Paratroopa event triggers in Monstro Town, the Paratroopas will not appear when you go to Land's End, causing you to become unable to progress in the game.
If you encounter this bug, you should go to the Mushroom Kingdom, then return to Land's End again. Doing so should make the Paratroopas appear as intended.
-There's no need for you to go inside the castle in the Mushroom Kingdom. The bug should be fixed if you enter the town around the catle.
-It's fine for you to use the map to travel to the Mushroom Kingdom.
-When returning to Land's End form the Mushroom Kingdom, you can either use the map or the "To World Map" option.
A software patch to address this bug is being planned for release in December 2023.
