Herbivore_Medium empty inclusion list… means they won’t attack anything. That makes sense to me.
As for Herbivore_Water… I don’t understand why it is an EXclusion list… I would have expected it to be an INclusion list that was empty (why would water herbs attack anything?)
Maybe it’s a bug? I mean, I noticed that Sauropod damage type is herbivore_medium instead of herbivore_large… so maybe they messed it up and meant for herbivore_water to an empty inclusion list.
