Group share Herbivore quest

Allow for the entire group to be able to get credit for the herbivore kill quest as long as they put damage on the herbivore. It would make the smaller carnies and juvies to be able to have the chance to complete it, as long as they got a hit on the herbivore and are in the group.

Not really sure how that could work but when I'm a carnie, either me or some of my friends are struggling to get the quest complete when the entire group is fighting a singular herbivore.
