As far as I can tell, any worlds that feature Yama hand menu, the hand menu currently doesn't work in the beta. It is unable to be brought up by its usual means of double pressing left hand trigger. The prefab appears to load on world startup, as i've seen the menu appear on my hand for just a short moment, but then won't appear again at all. Provided are two worlds I've seen this in, both are uploaded by me (I can't remember any other worlds that use this prefab, though i know there are some)
