I've just hit tier 3 crafting stations, and I'm still unable to craft any augments for my crafting stations, Tier 1 - Tier3. I have unlocked all of Tier 1 and 2, but the unlocked recipes from the progression tab don't appear in any of my crafting stations, regardless of Tier and Realm.
you build augments just like you do crafting stations. Place them near a crafting station for it to get the bonus.
