Sims Aging Up Are Getting the Weird, Creepy Looking Limbs

This happens when I age up my newborn though child sims and then travel to a new lot shortly after. In one case, I came back to find my recently aged up toddler and his icon reverted to his infant self, but had the creepy distorted body/face. In another instance, I traveled to another lot with my recently aged up teens and at the new lot, they reverted back to their child selves even though they had the capabilities of teens. They weren't distorted like the infant/toddler, and reverted back to their teen selves when I went back to my home lot. Overall work around (similar to the "infant milestones not completing after going to non-home lots) is to switch gameplay to another household and then go back to the original and everything is fixed, but this glitch is incredibly weird and annoying,
