I wrote earlier about how alien sims get rounder ears when aging up from toddler to child. I think I have found part of the problem. I noticed that alien toddlers and alien children don't have the same number of presets for ears. Alien teens and up have the same number of ear presets as toddlers, but the ones they have look like the ones for children plus one extra.
Ear presets for alien toddlers:
Ear presets for alien children:
Ear preset for alien teen and up:
Toddlers and teens and up have 6 presets for alien ears, while children only have 5 presets for alien ears. Not only that, they also don't seem to be tagged similarly between the ages. Marked in green are the presets one of my alien sims have for different ages, and there's a lot of difference in look between the preset he had as a toddler compared to the one he got as a child. Also, his ears are only pointy when he's a toddler, from child and up he has round ears despite the preset being pointy. The same happened to one of his sisters, they have the same ear presets. Their other sister has another preset, she keeps her pointy ears when aging up. So, it seems like the presets aren't connected properly between toddler and child. I assume there's something like that going on with the rest of alien genetics, hence why their faces look very different between ages.
Edit: Added numbers to the pictures, to show which presets are supposed to go together. Notice that my sim switches from preset number 6 to number 4 when aging up to child. Also notice that preset number 2 is missing from child aliens.
