Strange belly physics behavior [Skyrim VR]

[Kadavre]

Hey guys, I've been using the standard HIGGS+VRICK+PLANCK and for bodies SoS, CBBE, CBPC, CBBE 3BA and XP32 with FNIS, thus enabling physics collision with touch. The problem is: when I play an scene with SL and there is penetration, the belly of the characters stretch a lot, like they're being raped by a horse. lol

 

I THINK it's a collision problem between SoS and the rigs from the skeleton or something like that, but I'm not sure and kinda afraid to start removing and changing load order now that my game is stable. I tried reinstalling CBBE and CBPC and tweaking with the physics options, but even selecting the belly with less bounce the problem persists. 

 

Anybody had any problem similar or know what may be causing it? I tried searching on google with no results.

In my case, a follower's belly hangs to the floor when she's nekkid. If I turn a corner and see her, she's normal then as soon she registers, her belly stretches down like a curtain to the floor. I'm stumped.
