Yep. I'm not a vampire fan so I went and cured my vamps with vamprocillin. Unfortunately, they still do the Bella Lugosi walk (left arm hiding mouth.)
Since I couldn't get them to act normally, I made them marry each other and moved them into the old vampire mansion downtown. Now I'm waiting to see if their kids walk around all campy.
Does anyone know how to fix their walk or is that hardwired into their characters? I used InSIMenator and selected normal sim state and normal sim walk. nuttin.
