The "Maya" and "Shey" label doesn't mean you have to use those specific characters. Those labels are basically just the body type. "Maya" basically means the girls that are the smaller body type and "Shey" means the girls that are the larger body type.
Well they could have simply mention that instead of just the girl name :/When the scene list says 3x Maya + X it means that you need 3 girls that use the same body model as Maya, which are quite a lot.
the same goes for Shaye
how i msuppoe to know that maya + maya + maya + max = max with any girl that use maya bones , when on the same list there is some maya + max, tali + max etc.
why not just go like
girl type A + boy type A
girl type B + boy type A
etc.
instead of saying girl name wich make thing confusing -_-
