[FIXED] Missing Baby Skin Tones

I had this problem back in November 2016! I do have old archived simstagram pictures to prove it! I also used to have one of the baby glowing red on the family portrait, but apparently I deleted it :/

Here are the parents. Dad is red. Mom isn't.

Here's the baby. He is dark and not red.

Here is that exact baby aged up to child. He IS red.

This has gone on for a long time, since even before toddlers.

like the title says, the baby's skin doesn't match, but it's different than the usual "white/mixed parents but dark skinned baby". i was experimenting with the red miscellaneous skin tone to see what color the baby would be (no mods). it came out to be brown skinned, but the thumbnail and gallery show the baby being a bright red, brighter than the parents are, and the diaper it's wearing is red too. i was wondering if this happens in anyone else's game or if there's a fix? (pictures provided)

I just tested this. Two green parents got a green baby, but the two red parents got a brown skin baby, although the thumbnail down below does show red. And they did got their red skin when they became a toddler.
My guess is that the green worked because it was probably added with the alien babies. And since there are no red aliens, that one got left behind
