No, wizards and warlocks get the regular feminine spectral assistant, so Bonehilda's what you get whenever anybody casts that spell.

I'm still having the issue, mostly because I can't figure out which red hair is glitched, since all the textures are the same. I know it's the grocery delivery guy, but that's about the extent of what I know. However, don't worry about it if you're on vacation! Go have fun being on vacation. (Unless you want an excuse to stay in and poke Sims files. It's your vacation, you do what's most fun for you.)

The maid default has a problem, too, but I think that's because the game won't look at a multi-binned hair where it's used to a regularly-binned hair. But instead of showing up weird, that one shows up as the longsimple, like if I'd removed the custom hair she was using.
