@haykam is haven't seen any error, the recipe seems to be loading just fine but the recipe does not work.
Okay, I made further testing, and yes items in glowing items frames glow, but the text does not unless the text is dyed. I will modify my bug report.
Then why they specified that all Clusters can be Silk Touched at any stage if there is only one cluster stage?
@Greymagic27 I updated the description to add that.
