Hello, are you sure that you deleted because I tried to sell my adobe maker or whatever it's called and it wouldn't let me. I have noticed that I can't find my carpenter and I know that I had it before to make horseshoes and now it is missing.
You might have simply placed it in your Inventory chest by mistake, Not the regular items one, but your actual chest that offers you one or 2 free slots, and the opportunity to purchase a few more slots with gold. When "viewing" your items, when you 1st tap on the chest icon. Tap on the button on the top left that says Inventory. Any items you may have put in the chest while editing where they are placed, will be here. Hope that helps! And good luck!!
