If you create a Wild Orlan and make it all the way to the character appearance customization screen, the option for a head doesn't appear. I'm not sure if that's intended.
If you back all the way up to race selection and switch to Hearth Orlan, the option for a Head appears once you get back to appearance customization, except clicking it does nothing. Clicking Next from colors does nothing. You have to skip over it to Voice in order to continue with the character customization.
