Having the same issue here with both Warsmith and Master Armorer at the same stage.

Note:

  1. Like Shazroth, I was already wearing some epic armor when I had the journey active.

  2. Both are stuck at the last step.

  3. In the description for “wear a piece of epic armor” step in Master Armorer, the text says "craft an Epic Armor in the crafting panel of an Armorer’s Bench;

  4. and the previous step for “Craft an piece of Epic Armor” the text says to “unlock an Epic Armor from the knowledge menu”.

  5. Both of these steps in Warsmith seem identical but lack the description in the journey steps text information.

  6. Also tried adding a mod to armor piece (for Warsmith) Just in case the step was supposed to be the same as the Epic Weapon step to modify weapon.
