[V] Infant vampires can be seen in mirrors

As you can probably see in the attached screenshot above, but my sim's daughter (who's 100% a vampire (both parents are vampires))  can be seen in the mirror. But her mother (who's stood directly in front of the mirror) can't be seen in the mirror. Honestly, I don't know if this is intentional, a bug or what. Yes, this is the best angle I could get, I'm afraid.

One other thing: Yes, I did disable my mods, rebooted my game with my mods still disabled, and this "bug" (honestly not sure if this is one or what) still occurs.
