Did you use the cas.fulleditmode on cheat to change him?
I don't think this feature is for curing already existing occults and changing them into a human or another occult. I'm fairly certain it is just meant to be used while creating new sims. Similar to how switching traits around using the cheat doesn't properly remove the old traits. I think to change the occult sim's status you are supposed to use the in-game mechanics to do so.
Someone can correct me if I am wrong, though.
@JradSims @Rebekyy @T0RN_x to fix this; type into the cheats menu (Shift + Control + C to Open it)
Type:
1. TestingCheats on
2. traits.equip_trait trait_occultwerewolf
3. traits.remove_trait trait_occultwerewolf
And the trait should be removed.
Looks like this bug: https://answers.ea.com/t5/Bug-Reports/UNSUPPORTED-Changed-Trait-Wrong-Emotion/m-p/3477285#M1068 where the trait isnt properly removed when you use cas.fulleditmode on
