3.0.31: The red prince is digging with his hands even though he has a shovel in his inventory. Other chars use the shovel.
That's because The Red Prince is a lizard, and lizards have a racial where they can dig with their hands. It procs his racial, because he doesn't NEED a shovel. There's no mechanical difference between Lizards digging with their claws, and anyone else digging with a shovel.
