So hopefully you can tell what I'm talking about and I've cleaned out my CC and saves but it keeps happening. I should mention that this is fairly recent? It hasn't been something that occurs 24/7 but I'm fairly certain it started after I used a pose pack n pose player. I uninstalled this script mod a while ago.
