I am on Thaumic Skies server and using the mod EvilCraft. The GemStone Torch when placed down looks weird for what it is, but also it doesn't use up any torches out of my inventory too. Lastly it doesn't do what it is suppose to either. Its suppose to block Vengeance Spirits for up to 15 blocks.
It's placing them in a stacks on stacks pile like when you place ingots on the ground. It thinks they are gems since the item name starts with gems. I'll blacklist them
