Necks are broken for everyone when crouching

I just got on vrchat after the new avatars 3.0 patch came out, then as my friends saw me crouch they say my neck would flip out and just do insane moves like going 180 degrees, although when I see myself in the mirror that doesnt happen, so I asked a friend to crouch and it does the same to them, this happens with desktop users and VR users alike, im writing this to see if theres any way to fix this, whether we need to update our avatars or if this is just a VRChat thing that needs to be solved

ive noticed, currently trying to figure out how to fix
