I am having trouble with the Attachable Wings component of 1PP: they turn the wearer's torso and head invisible. When I equip them on an elf, whether the elf is wearing a robe or armor or nothing, the head and torso disappear, though the legs and wings are still visible. If I equip a weapon, the weapon also appears. The avatar appears in full if I use CTRL-J to move the character someplace, but if I move anywhere or take an action, the torso vanishes again. The paper doll renders correctly.
I have tried installing everything in 1PP, as well as installing only parts of it, and the problem persists. I am using SCS, Tactics, and Spell Revisions, but no other mods.
