hi. you are in the wrong section. But first of all the other bones do work. and the current version isnt bugged. here is a video I made a while ago on how to use it. I made this video very quickly so I might have missed some things. https://youtu.be/q56F15yeyTo
Also here is the link to the actual forum for mecaface: https://www.mecabricks.com/en/forum/topic/1776/2

Hi sorry and sorry again, it works perfectly fine. I found that video and it was very helpful. might be worth adding that video to the product page for noobs like me

Hmm probably. ill make a better one if I do.
