I have been having this problem with multiple crafting recipes, like steel and chickens. Steel wasnt a problem due to the blast furnace, but I cannot make a log chicken. I have deleted the pet rock mod, which was a suggestion from another thread, but nothing changed. i have also had to delete ProjectRed, due to some conflicts causing my game to crash. I have deleted and reinstalled a new version of craftTweaker, but now my game just crashes. Has anyone found a fix for this problem?
