hi im having the same problem as bkeul. ive checked my load order and any possible conflicts and could not find anything that could be causing this. ive been playing with high poly heads for a while and this is the first time this has happened to me. the only other vampire centric mods im using are sacrosanct, dawnguard tweaks and enhancements and better vampire fangs and eyes for the blue effect. uninstalled all individually and at once and even tried a new save without them, no luck.
any help would be greatly appreciated
edit: having read a bit more thoroughly on the mod page it looks like the vampire face fix simply does not work at the moment and needs to be updated.
