SOS Full - Body Errors

[=C=]

I'm at a loss for words.
I would like to use BD's Hoodies, but it has dependencies on SOS Full's Core.esm. However I can never seem to get it to work. It never worked for me in Classic Skyrim, and it continues to not work for me in SE.
Basically what happens is I will go to start a file (I don't have any saves from old PCs. They're gone), and around the "Presents" part of "Bethesda Game Studios Presents SKYRIM" screens, I can hear an "unequip" noise. I look around and sure enough everyone (except Ulfric Stormcloak) is without their armor. Helmets, Greaves, and Gauntlets are fine, and earlier I even had a mod that added in a layer of Underwear to all NPCs (but the bottoms have since stopped working). During my confusion I accidentally ran SSE without SKSE, and thus SOS wasn't enabled, but all the armor was back. So I tried to see if SOS Light would work. The Armor worked, but it didn't have the proper files for BD's Hoodies to work. I guess if push comes to shove I can deal with lore-unfriendly Khajiit peen, But I'm still baffled why this persists from Skyrim Classic to Special, and why none of my friends seem to have this error.
I will also note that at one point I decided to use the tfc command to get a better view of everything else, and I noticed that some other bodies (I think the Dunmer) were completely invisible When the one NPC tries to flee, after he dies the bottoms from the underwear mod show up, and what seems like an outfit flashes in and out of existence sporadically. I also tried to make a character to see what would happen at this point, and a few of the bodies were just completely wrecked. The only things I haven't tried yet is A: Starting from scratch, with SOS and it's dependencies first, and B: Seeing if making a file first and THEN adding SOS works.

At this point I'm just frustrated because I can't find any solutions.

Edit: I seem to be able to hit the "reset SOS" option in MCM, and all loaded NPCs will get their armor back... but once they are unloaded, they lose it. And any newly loaded NPCs still don't have their armor. Make of this what you will.
