RaceMenuMorphsCBBE.esp form Body Slide (may 2016 update) when in showracemenu, and only when naked If I adjust my CBBE sliders, usually instantly sometimes after a few shuffles, I get a CTD.

I've a fuck tonne of mods so there's no point posting my LO, so gonna start turning things on n off in MO, what variety of mods should I be looking at, that might have some bearing on what RaceMenuMorphsCBBE.esp does?

 

Note it works fine on a clean/very simple MO profile.
