problem with fractal exotic weapons!!
If you had these weapons before the Fractured update (which is the only way to get them), they will remain as weapons without stats. Anet has said that previous fractal weapons before patch will remain like that because they can’t convert them to skins. Only way to apply them onto weapons is to use a fine transmutation.
Ones you got prior to the fractal update will not be skins.
