Questions about Ordinals


I have about few questions about ordinals for crafting categories…

  1. Are ordinals implemented?
  2. What happens if two crafting categories have the same ordinal?
  3. What happens if there are missing ordinals? (ex. 1,2,3,4,10,11 -> 5-9 are missing)
  4. What if a crafting category doesn’t have an ordinal?

Thanks for helping =]
