I'm just about to finish the Tai Bwo Wanni Trio Quest on RS3. I already did everything and gave the seaweed sandwich to the guy. I already did the marinated Jogre Bones part, but I'm having trouble getting the crafting manual. I already have the 2 Karambwan Vessels but it keeps saying "Nothing Interesting happens" when I try to use the item on him. I should be able to finish the quest within 5 minutes but this part is acting weird for some reason. Please help.
