When I started the game the physics were really good and actual quite realistic but i noticed later in that the Breast physics just straight up stopped working at all and are now completely still.
I’m not entirely sure what caused this, I read it could be anything between swapping chest pieces to being knocked down by an enemy so I can’t really type any steps to reproduce as I did not notice this until I was changing my characters clothing.
To answer that question, no, more times than not they never really work again. I mean yeah pulling ones bracelet can MAYBE fix broken physics, but I’ve been playing this game since release and this has always been an issue. Hair, breasts, clothing, armor - all eventually just freeze up. And it can happen sooner rather than later if you change your toon height at creation.
