I have already reporting this bug ingame to Ez & understand it will be passed along to dev for hotfixing. I wanted to let everyone know incase anyone just so happens to be planning to be crafting in the meantime.
The Expert Armorsmithing Hammer is requiring the wrong amount of ingredients for 2 items.
When trying to Craft Expert Elementalist Pants or Expert Elementalist Shoes, it is requiring 3 of those Patterns instead of the normal 2 patterns required by all other craftable Expert lvl gear.
