The W.I.P. Tapestry kit returned none of the kelp, pig skin, and beefalo wool I placed into it when I hammered it. This really stinks when you wanna move the tapestry kit halfway through constructing it since you lose all your materials put into it.
1. Hammer Tapestry Kit
2. Notice none of the stuff you built into it(kelp, pigskin, wool) dropped back
