I just updated my game, and decided to make a new save game to have a fresh start and see what the new update has to offer. As I was taken to the CAS screen to create my family, I noticed something was off. Whenever I change the voice or randomize a sim (or any other action that would cause the sim to talk), I saw that my sim would no longer do the talking animation. The sim has the same body and head movements as prior to the update, but all sims no longer move their mouths when they are supposed to be talking, and the audio just plays over the sim moving.
I believe the problem has something to do with the addition of modified teeth, however that's just my guess, and I don't know for sure.
I appreciate any and all advice and/or solutions that are provided. Thank You.
EDIT: I don't use any mods, so the issue is not in any relation to mod use
