What craft are you testing?You dont need to use the correct tools or mats while crafting for an outcome of what you want.
Did you have incorrect tools or materials or both? I'd like to duplicate this.
I'm doing some work with stacking and containers, so that players can carry empty containers in their pack. It's not quite finished yet so these issues you mention are my focus right now.
All specifics are appreciated so I can duplicate and fix the problems. (You can email me with exact steps, that would help).
Thanks!
