Shoulders/arm clip through ground

[Park Simp]

This is an issue I get on oldrim as well as SE. When my player ragdolls for whatever reason their right arm clips through the ground and slight shoulder contortion.

 

The strange thing is, when switching race the issue seems to go away for some time however will come back eventually.

 

 

I'd imagine it has something to do with XPMSE however I'm not sure where to start. I've tried reinstalling everything I can think of related to body/skeleton, using LOOT etc. I do have a lot of mods, load order attached

 

Thanks in advance.
