sims do react to vamps they ruin every vamp-human relationship for all the wrong reasons-) one growl or vamp hand movement in a public place and that's it other sims avoid them more out of disgust than being scared so I agree it makes sense for other sims to be scared of them but for the right reason as a predator lol I too thought we would get a fear emotion from vamps but apparently not.
@Simmingal
I like to play my supernaturals together so vamps-witches/warlocks and soon to be mediums but there is no way no matter how I have to find a way to get around it are any of my vamps going to be scared by anything/anybody including a magic spouse using spells or anything else out there in the world that may come along either lol :)
CelSims Pointed me in the direction of a mod where as player can choose how other sims react to each other via the settings in the mod. I have had a quick look at it tonight and am defo going to try it out.
