[WickedWhims] Sim won't keep her glasses on when stripping

[PyrasButt]

I'd like for my Sim to keep wearing her glasses even when removing the rest of her outfit (during nudity interactions and activities, not when bathing), but I can't seem to get it to happen. From what I understand, using the "Specialized" setting for the "Completely Undress Yourself" command is supposed to retain the accessories and makeup of your Sim's outfit (described in the third bullet point here: https://wickedwhimsmod.com/nudity-settings) but it doesn't seem to be working. Even if I check that box while she's dressed up in her full outfit with glasses, she still takes them off when she gets naked. Is there a bug, or am I doing something wrong?
