[regression] No. 2 Type B leggings not correctly displaying "butt enhancement"

[plasmacutter]

It seems a 5.15 "fix" for clipping on a tiny handful of outfits has "broken" the "bottom enhancements" on No2 Type B Legs for a huge majority of cases, including when used with the rest of the No2 Type B glamour outfit.

Date & Time: since 5.15
Frequency: Always
Character Race: All (not Lalafell)
Platform: PC and PS4
Community Impact: These leggings were worn by 1 of every 2 player characters pre-patch. The visual malfunction has caused players to cease almost all use virtually overnight. There are long threads about this in the EN and JP forums, on reddit, and on some gaming media outlets. The playerbase is widely unhappy over this.

Steps:
1. Equip No2 type B bottoms
2. Equip any item that would hide the skirt on "quaintrelle's ruffled skirt" (this includes No2 Type B dress that was supposed to go with the pants!)
3. Before 5.15:

4. After 5.15:
