Hello members of minevast, I recently realised that if you click a checkpoint sign on parkour, the checkpoint is set to where u stand. But if you are able to click the checkpoint from a different position, you can spawn there. I'm not sure whether this is an accident or on purpose, but if it is an accident and is not meant to be, then I would suggest setting the command block sign to 'Spanpoint (Specific Coordinates)' rather than Spawnpoint @p (nearest player)
Many Regards,
