I have 5 Rare Aggressor Kits, and 3 Rare Swifthand Kits. But when I go to the crafting window and see the green box marked "Add Crafting Kit", neither of these come up as options to select. I can use Assault Kits (that I craft myself) or Refined Range Kits (that I craft myself), but I don't know how to use the rare component kits that I get from the lockboxes.
Is there a trick to it, or am I missing something?
