With the new update and Enchanted by Nature, we’re now able to use various body parts from different occults, including ear-types. Unfortunately, adjusting them would revert the ear back to a human Sim when done so while in Detail Edit Mode. It doesn’t seem to happen in the regular zoom of Create-A-Sim.
I don’t know if it’s intentional, or if it’s a bug. Maybe someone knows and can help. I have only updated the game and gotten the EP, no mods/mods disabled when capturing the clip sample shown above.
