male upper body enhanced chests are not working

[Rosario Blackthorne]

Hello, seems something changed and most of my guys got the same issue with the topless outfit.

I'm using several upper male body meshes that were set on guys, it worked before but something changed, not sure what. 

The enhanced upper body is now shown only when they undress shirt or other upper body clothing or they are getting completely naked, but not when they outfit like workout, swiming suit, sleeping clothes are se to be topless, these outfit uses default version of the male chest not the enhanced one. 

it worked before, not sure if they chests are outdated or what changed. 

any suggestions, tips?

(probably not a helpful answer)
In sims4, body presets, sliders, etc. change with morphing, so they can be adapted to all clothing. For example, my TOP bodypart, which is a direct 3D edit, does not reflect the information on the rest of the garment. This is because nakedness, or there own nakedness made from them, is also a form of clothing.
What you are using is probably top data that is a direct edit of the 3D. So if you change the outfit, you lose the 3D information of the sim.
As I said earlier, you can reflect this in other clothing as long as it is changed by body presets, sliders, etc.
