I see everyone talking about upgrading their animal sheds and bird sheds to stronger material, but I'm not sure how you are doing that. Do I just have to have Gotz build a new one in a different spot, or can he use the same building but upgrade the material. Thanks guys!
If you want to upgrade animal or bird sheds, you have to call Gotz to demolish it, or let a storm do it, then call Gotz and have him build another one.
