Apparently, Ancient World Crafting got updated!
It's kind of hard to explain how it works, but let me try to explain.
So, I have 625 Clean Rubies. I can now either:
-Craft 125 Pure Rubies in 125 button presses.
-Craft 25 Fine Rubies in 25 button presses.
-Craft 5 Neat Rubies in 5 button presses.
-Craft 1 Bright Ruby with the single press of a button.
If someone else can better explain it, I'd appreciate that very much!
