Far as I can tell, the VampireRun walkstyle is somehow hard-coded to having the Vampire Trait. Can't seem to track down in what way though. I figured maybe it's to do with the default vampire walkstyl...
@AHolyToilet Sort of. The Child Trait ability/functionality is more or less working (it'd just be nice if I could get it to reliably do the panic run, rather than jogging). I've also been intrigued by the prospect of trying to get the Vamp Run to work beyond being a Vamp (which was the main premise of this thread), but not having much luck with it.
