For some challenges, for instance Clothes Crafted, it's very easy to get it by crafting tons of Burlap Shoes at 10 cloth a piece. For weapons crafted, you can probably craft Wooden Spears all day. This is especially an issue when players receive kits for leading in the categories.

It would be great if you could exclude items from the list of craftable items that qualify or potentially be able to specify Tier 2 and up.
