Nothing is more frustrating than getting through a crafting progression bar just to have it fail because you either didn't have the right tool equipped or you are missing the initial crafting item. Example...cooking a boiled chicken. It doesn't tell you that you forgot to equip the cooking pot until you go through the hellasiously(sp*) long progress bar and by that time, your billets are mostly wasted. Another example is building the tiny shack, You start the construction just to find out that you need to have a construction log in your inventory before you start building. However, nothing is there to really tell you that either. Just saying, should check prerequisites then complete action, not the other way around. However, it is your game so :P
