With my sims created before the 10/22/24 update I noticed it always happens on my teen and older vampires and spellcasters who are employed or have been employed at some point, and with teens and children it also happens when joining an after school activity or if they have ever joined an after school activity at any point. This happens to sims saved in my library as well as ones already in live mode before the update. It also happens with brand new sims I create after the 10/22/24 update once they get a job or join an after school activity. The eyes and vampire features on newly created sims will work fine until they get a job or after school activity and then I exit to manage worlds or enter cas in any way with or without the cheat cas.fulleditmode. I have noticed with brand new sims this bug has happened with active careers, such as the reaper and scientist career, as well as rabbit hole careers, such as the culinary career and the scout after school activity. I have high school years so it did not happen to my teens when I followed them to school but I did not test it with sending them alone. With my brand new sims it doesn't matter if my sims have actually gone to work or their after school activity at all. Once my sims joins a career or after school activity through the phone they automatically become bugged but I don't notice it until I exit to manage worlds or enter cas mode with them. I have not noticed this bug with vampires and spellcasters saved to my library before the 10/22/24 update that have never had any job or after school activity at any point.
Also mermaids saved to my library before the 10/22/24 update that had occult eyes on their human form, now have human eyes automatically when opening them in cas, and with those mermaids only, if I choose to copy the mermaid form face to the human form the occult eyes will get copied to their human form in cas, but the human form occult eyes automatically turn into human eye colors once I place them in live mode.
