Realm of magic - Promiscuoso spell seems broken

[wktrcwl]

Hey, recently when I was playing with the Wicked Whims mod, I started using the native options to convince sims to have sex, combined with the Vampires and Realm of Magic expansions. In Vampires, everything works as I expected. Calling the interaction makes the sim accept sex with the playable sim every time. However, when a similar interaction is performed by a wizard in Realm of Magic using a Promiscuoso spell, the NPC rejects my sim for various reasons. Is this a bug or a feature? I would expect that in the mod's code, this interaction is just a copy-paste, but wrapped in a different name.

 

Is this the right place to report it as a bug?
