Horizon somehow overwriting Bodytalk3 and FusionGirl meshes

[TempoDanMan]

Not sure if this should go here, but I was wondering if I could get some technical advice here?

It seems like the BodySlide morphed outfits for FusionGirl and BodyTalk3 work fine, along with physics, in my game. But once any clothes come off you get a vanilla non nude mesh for both male and female character models, where the skin of the female character bodies seems to be the FusionGirl, albeit horribly distorted.

After extensive trial and error to make sure I wasn't screwing up the BodySlide setup somehow, I came to discover it's something about the Horizon mod (v1.9.1 for a Fallout2287 gas masks compatibility patch) I have installed which is causing this strange behavior. And the moment I disable the Horizon mod I get the expected nude FusionGirl and BodyTalk3 meshes with skins.

Does anyone recognize what Horizon might be doing here that I could somehow patch with FO4EDIT or something? As far as I can tell the mod doesn't actually replace any character meshes, and FO4EDIT seems like a tool which lets you make compatibility patches between .esp files. I don't want to get rid of the Horizon mod since it's kind of the core of my new Fallout 4 playthrough. My BodySlide Output is at the very bottom of my mod list load order as well, while my horizon mod is near the top.

I've attached an image showing what female bodies look like when the Horizon mod is active in my game if it helps at all.
