Hello, first off love the mod and can't play without it especially with other mods that don't have good crafting documentation. Now onto the issue I'm having. I can't seem to get the big recipe book to open when I click the book icon. I can use the craft helper button when I right click items in my inventory perfectly fine. I am running windows 8.1, Zomboid build 31.13, and craft helper 1.5b. I hope you can get this fixed as soon as possible and keep up the good work. -Dvine EDIT: Turns out it wasn't your mod and it was Hydrocraft, which is currently the only other mod I'm using. Hopefully i can figure out what in Hydrocraft is making it so your recipe book won't open properly.
