Carpenter Crafting Error Alpha 8

So I in the middle of crafting some items, via the carpenter, I decided to change which items to be crafted next. Then I got an error, and the carpenter refuses to craft anymore. I hate her for it. I want to smack her, but I’m not abusive. What can we do to fix her bipolar mood? Unique User ID 82aded1c-74b2-11e3-adfe-0002761c45a2. I tried to attach a screenshot, but it says that I can’t. I will just go cry in the corner. :cry:

I’ll explain the error message.
