So I've been finding that I can't get Morph Bellies to work at all, even following the instructions to the letter.
I'm using ThePootis12's outfit conversions, which I built in Bodyslide using the group Coldsteel Conversions. I batch Built them, with Build Morphs checked.
It's not just the Morph Bellies either, I've been finding that I cannot get Macross or Skeptic's Bellies to work either.
I've tried building the category EquipBellies NoSliders, just regular old EquipBelies, and EquipBellies all sliders, and I can't get any kind of belly to show up when I devour prey.
I'm using the most recent version of Devourment Refactor.
This is my load order.

All other morphs are working fine. Weight Manager works fine, and is able to display changes to any of the sliders.
Can't get any bellies to show up, equippable or otherwise.
EDIT: I couldn't get the morphs on ThePootis12's conversions to work at all on the 5/27 update but all equippable bellies were working fine.
