I tried converting Leefa, but for whatever reason it keeps crashing MMD (probably bone related).
It opens normally in pmxe and It actually functions properly in VMDviewer, even the boob physics are good for once. So i'll leave it up to you guys to solve as i've already spent more time on it than intended.
