So, I was leveling JC today, and I DE'd something I made, Carnelian Spikes.
Now, I usually get made 1 - 2 lesser celestial essences, but for this, each time I got atleast 1 - 3 greater celestial essences, or 3 - 5 dusts.
I'm not sure if this is a bug, or working as intended, but it sure makes a lot of gold on my server.
