I tried to simulate profits for Azureweave Bolts with Lesser Illustrious Insight, but numbers in "CraftSim Average Profit" window did not change when I added it. When I manually changed skill value in "CraftSim Simulation Mode" window, calculated profit also was not updated.

IIRC this worked about month ago.

Version: 14.4.1

I played a bit more with this and looks that I did not pass some threshold. So not an issue.
