Here's the problem... I made 3 mineral harvesters and 2 windmills today, (one of each at the public crafting station). All were made with the specialized crafting tool. I didn't get any experience for any of them. It was my understanding that I'm supposed to. Did I do something wrong, or did I just get bitten by a bug?

oh.. I see! So, harvesters don't add to crafting pool... now I get it! thanks.
