Mass crafting will change what you're crafting when the previous recipe becomes uncraftable.

Not sure if it's caused by my sort method being "craftables", but if you're mass crafting and aren't paying attention it'll start mass crafting whatever's next in line without requiring player input. It can be worked around by paying attention and releasing the button as the final craft is in the animation but I think crafting something new without an explicit input to do so should be patched out. Feels like an oversight.
