Firestorm 21 stuck in the back and cannot move forward.

@GeneralWilhelm22 Putting aside the lack of response from others, a player ending up at the edge of the world does so because they're inexperienced on such a small world. This has happened in the past. If you look at what badges players have that are stuck at the edge of the world very few have recent Firestorm first place (or any first place) badges. This indicates they knew not to jump at the start of the small world without checking the likely possible routes back.
