When crafting new items such as the first iron pick axe, the item is not automatically recognized in the inventory. I found that if I go into my inventory, remove the item, then place it back into my inventory, it recognizes the item. This means that when I receive a new item (such as smelting iron ore to ingots), the recipes are not updated (i.e. the crafting table does not show iron items).
