Vysn posted that he fears a number of things with regards to the update.
Namely that people will complain about not have enough materials, they will complain about there not being a Craftron and, most interestingly to me, they will complain that you will not be able to kill or gather at the same time as crafting. I assumed it would be a timed process like building parts of your house, but it seems like crafting will be a stamina based action.
