Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting Crashing on crafting a modded recipe

I was trying to make a skill book craftable but whenever I try to test the recipe I get the error "Couldn't load UI icon from texture atlas: 'unknown_CharIcon'!" then the engine stops responding. I've made other skills books combining the same items but when I change the result to the other book I get the crash. Has anyone fixed this issue or have suggestions? (Im not using any custom icons)
