I have this issue as well. Not only the mouth is not syncing, there's the CAS zoom out issue. I don't know what are the others issue I may not identified, but so far the issues are two: mouth and zoom out during CAS
Thank you to the person who started this thread. I hope all who are experiencing a similar issue will report it here. I cant imagine it being an isolated issue for a few Simmers.
I have been having the same two issues since a few days into the toddler patch. Sims in CAS and live mode have no lip movement when talking, singing or interacting with each other. I also have the CAS, undo jump to full body issue, but the voice and mouth sync issue is more devastating to me. It is hard to play with my sims talking to each other, flapping their arms around with their mouths completely shut and you can't see the old or new teeth you choose. The most frustrating part of all, is not being able to see the fangs in the new game pack I purchased.
This bug where sims mouths no longer move is driving me mad, especially with the new karaoke machine, I loved watching my sims sing along. I hope this gets fixed asap.
Same here , my sims won't animate their mouth while singing / chatting / complaining... Poor things are stuck with glued lips. I don't know how my vampires will feed now.. lol
