Playing on modpack ATM 9 1.0.3. Hellshelf of sight shows up in JEI with the recipe however when you put the materials in, the item hellshelf of sight doesn't appear making it uncraftable. I am able to grab it and place when in creative but just can't craft it. Recipe shows 1 potion of night vision (3:00), 2 infused hellshelf, 4 blocks of gold, 1 spyglass and 1 eye of ender.

Please report recipe issues in modpacks to the modpack and have them delegate here. It's far too possible for there to be something interfering.
