Your example has nothing to do with the breast size being big. It happens with both small and big breasts, @Blyker .
I covered that bug in the video I posted.

Wanna find out? Sit a t4 dancer with min breast size on a bench. Her breast will magically grow! Take her out and the breast will go back to its intended min. size.

You are talking about an unrelated bug reported a long time ago. Pay attention to what you read.
