You really need to address the body size of teens. At the moment they are just adults or children with nothing inbetween. This cannot be about sizing, because you have 2 sizes right there. Just make 3, with the one in the middle being sized mid-way between the two.
Thanks
There’s already a similar topic. 
Perhaps multiple topics will help InZoi to understand that a middle height difference is important to the game, they will do something about it. If it’s all buried under a single topic (nobody is permitted to start a new thread on this topic without being shouted down) then InZoi can simply ignore it. For example they can say: “there’s only a single topic on height difference, therefore it’s not important to users.”
I think height difference was raised at the very beginning of development and has been firmly ignored since then. Even though we have 2 sizes (adult and child) we cannot have 3 (adult and teen and child) - this seems arbitrary and is quite frustrating.
