Thats what I figured. They were lower levels.Were they low levels? If so, it just simply means maybe their cp broke or the game stopped working and they haven't had a chance to level up and their membership ran out. That's my guess. I just recently made a Pirate and that shape wasn't available.
It was the body type before they got changed to the I guess you could say "non steroidized normal body type". My mom would always say: "Your pirate must have been taking steroids to get a body that shape!"
