I wanted to make it where samsite can damage the balloon, but players couldn't. I got it where samsite damages the balloon, but can't get it where players cannot damage balloon. I'll paste what is in my config file below so you can take a look to see if I'm doing anything wrong.

        "anything can hurt dispensers",
        "anything can hurt players",
        "players cannot hurt players",

        "highwalls can hurt players",
