Avatars upper body spasms violently when moving

Video example:

Hello, whenever my avatar moves, the upper body spasms.
It seems to occur more when the arms are fully outwards like a zombie.

I have checked, and there are no phys-bones affecting the upper body.
It does not occur on other avatars, which means it’s not an issue with my headset.
It has happened on some of my other avatars, from what I remember.
It also occurs on Quest, from what I remember
The avatar does have GoGo Loco, but it still occurs when removing it.

If anyone knows how to fix this, help would be appreciated.

Nevermind. I did some more testing and It turns out that since I had really tiny bones taking placed of the spine, neck and shoulders since I didn’t need those bones but VRChat did, those caused the issue. Scaling them up fixed it.
