Hm. Mine has it. He has both bat and run. Tried in both forms
It's always there
Can you try moving the Sim out and back ?
How much lore does he have ? Anything else different to the Sim where it works ?
Was the Sim converted/game made/CAS made ?
The sim in question is Lilith Vatore, one of the premade Forgotten Hollow vampires. However, today while playing I gave her brother Caleb Vatore all the same powers and his menu shows the "alluring visage" option - it appears the problem is limited to Lilith. I will try your suggestions, thank you!
