This is mainly focused on the "Hogsworth Quabbleball Arena Flying Map" where crashing into the blue borders can sometimes cause the players to glitch out of the borders and find themselves outsides of the area they're supposed to be, unable to go back in and complete the game.
A potential fix that came in mind was from the temporary minigames that involve elytras: When the player falls, there is a block to teleport him back.
If a checkpoint system could be added recording each player's nearest to finish line checkpoint that they passed, if they happen to glitch out of the border, they can just click one of those "teleport back to checkpoint" blocks and be able to continue the game.
