Steps to reproduce:
apply a smithing template to any armor
look at any other armor in your inventory (you might have to pick it up via clicking on it)
observe how it has the texture overlay
Expected result:
the armor looks normal
Actual result:
the armor item texture has a smithing template overlay
(I am not sure if this is patched but it was there before Chase the Skies)
