If you don't, the player can simply grab one townsperson and while holding them, jump up and down in the pen and it will just keep incrementing the score.
Also with scoreboard target score and leaderboard: if scoreboard max is 100 and the player reaches 100, and the challenge ends, the leaderboard will show them as 0 points since the scoreboard resets
So with both of these together on modeltrainman ribbit Asgard level I scored 300 points then stopped until timer ran out and it shows zero
