Just started my game up this morning and not long after departing windhelm I'm beset by an invisible saber cat. I can't see it at all so I toggle god mode to kill it so it stop bothering me. At first I thought this was just a one time bug but it's not. ALL saber cats are invisible and I don't know why. I've never put in any replacer mod for the saber cat nor any other entity for that matter. Does anyone know a solution for this or any preventative measures?
