Nalates it's still happening with many many classic avatars in the world wearing many different body shapes and most don't even own a mesh body as I didn't when this pic was taken with Only shape, skintone, system eye, and brows on replaced outfit and the issue is still there. I did try as you suggested with an alpha and then replaced outfit again with only shape, tone, eyes and brows and it's still like this as well as tried relogging and resetting skeleton and skeleton and animations so bare bones shape, tone, eyes and brows and still looks like this tried different shapes from various creators and all look like this broken body.
