PSA: Fix your child's loose tooth before aging her up to teen

I aged my child up to teen and then spent an hour in CAS perfecting her. Then when I went back into the game, her skin was black (not like the skin tone, like black black). When I went back into CAS she had been completely transformed into another person with none of my work.

Long story short, there's a glitch where if you age a kid up while they have a tooth issue, this will happen. You need to have them "fix loose tooth" before aging them up.

Hope I can save some others the time I wasted.
