Isn't the vamp sims allowed to drink from wizard or witch sims?

Checked it, the interaction is still there, I also added future sim hidden trait to the wife and the option to drink still appear. either something from your mod folder caused this (not necessarily from vampire related mods) or your intended target has buff that prevent from getting drank by vampire like pregnancy or something else.

Vampire cannot drink from teenage sims without mod, is your sims nephew still a teen?

I also have hybrid mod, the husband is vampire-warlock hybrid.
