On the horned head model: The horned head model is reserved only for Tiefling characters. If your character has this head model and is not a Tiefling, you will be asked to change your head model. Please contact your local DM to have your character's head changed if they do not qualify for it.
This kinda been a problem for as long as i remember. Wouldn't it be be possible to remove the horned heads from character creation? and if you select Tiefling as a reward then you will be asked if you want horns or tail added (not both).
