I am currently unable to craft Chitin or Nordic caved armor. There is no option for either of these armor types at the smith.

I have 100 smithing with all heavy perks from Steel to Dragon.

I have completed the main quest in the dragonborn DLC. The only new DLC armors I can create are Stahlrim and Bonemold.

I do not have the heartfire DLC, I've seen some videos on youtube and other people can craft ancient nord / chitin armor.

Do i need heartfire or whats the issue here.... I can buy these armors from vendors but when I go to my blacksmith there is no option to create them. The only issue this causes is when I take them to a workbench I cannot upgrade them to legendary without potions and enchanted smithing gear.
