I am having invisible npcs in exteriors only and sometimes they become visible when it me or sometimes when they dodge ultimate combat and tk dodge installed and yes y run FNIS and i have XPMSE, also if i save an go to main menu and load they appear (does not work if i don't go to main menu to load) already try modifying hdtPhysicsExtensionsDefaultBBP, and the hdt invisibility fix beta. the issue happens even before installing the book of unp, and before install any of the npc overhaul
