Stranger still: when installing Annika I actually got her to show amid my other Saved Sims, and her skintone did appear on her perfectly, only my Bodyshop and CAS both just refuse to list it among all the other available skintones I have. Curious about this, I installed Incubi to make a test, and both CAS and Bodyshop listed it at once, while still rejecting Loveless. So who knows. Perhaps this is simply a weird personal game issue.
