Yeah, that's known - needs spine assets tweak. Basically, loli only have flat size arm sprite set up, but not for small chest. I'll keep that in mind when I'll make more spine edits later.
Also, here's another question I do have, maybe someone can look into it (
Surgy ?)
Basically, it's about thigh size. I know there's a code in Assembly which makes "LowerBodyType" set to 2 (big thighs) instead of 1 (small thighs) if tits size is bigger than 1 (small).
Now, I tinkered with it a bit and it's not that hard to make it return 1. The problem is game doesn't have separate customization option for thigh size. Either it works in "auto" mode or set it to 1/2 only. Unique NPCs/slaves doesn't have this issue because their spine file comes with one thigh size.
So, my question here: can thighs customization be implemented via BepInEx?
