I have been using MLLY Mannequins for a really long time. I've not really had much problem with it.
I loaded a couple of house mods that I love (Elisdriel and Elysium Estate). Both homes include mannequins. It seems since I first loaded Elisdriel (I'm not blaming this mod at all! just saying this is what seems to have happened....) my mannequins across the world are now naked. Fine. I take off their gear and put it back on. It seems to stick. Sometimes. Randomly, the mannequins will be invisible. This happens regularly in my Hearthfire homes. It seems now to always happen in Elisdriel. I have a nice mannequin with a beautiful gown at the door. She was gorgeous for a couple of times, then once I came back and she was naked again. Dress her again. Go out, come back, naked again.
Does anyone else see this issue and what could be causing it please? I did apply the Vanilla Mannequins Script fix, but that didn't seem to do the job, because it's really only for vanilla mannequins, but I thought I'd try anyway. Any other ideas?
