muy buenas comunidad.
disculpen al actualizar plutonium me salio esto, que puedo hacer?; ya borre plutonium y traté de reinstalar pero apareció lo mismo

I've been looking for camouflages, and when I find them I'm surprised that most of them just give you the file and you have to put the name of the weapon. My question is, where can I see what is the code name of that weapon or if someone is so kind as to provide a list of each one?
Pd. Si alguien responde en inglés, no hay problema, solo quiero una solución
