I noticed this today because my lion just grew up, but if you take this lion https://www.lioden.com/lion.php?id=794188625318 and put her into wardrobe and make her an adol the vit 5 marking is barely noticeable. I didn't even know she had vit 5 marking because the marking is so unnoticeable, but when she grew up the marking just completely took over. :/

here's wardrobe links that should show the problem
Adolescent with barely noticeable vit 5
adult with very noticeable vit 5

I think this marking should be more uniform throughout all stages of age. I just want to make sure I'm not crazy here, has anyone else noticed this?
