I've picked up a bug that consumes the materials entirely when making something when the quantity of required materials isn't met for the creation of said item. Here's the example I had:
A stack of 60 flux and a stack of 8 Iron ingot, when on auto craft should produce 4 steel bars and have 12 flux remaining. The craft animation should only run 4 times and then stop immediately after that when it detects insufficient materials. but it doesn't, it runs for a 5th time regardless of the quantity of remaining materials, and will consume them but produce nothing, but I lost the 12 Flux = rage quit.
Perhaps there should be a slider bar that you can set to how many times you want the crafting animation to run, for example, (Using the same above scenario) I would have set the slider to craft 4 bars, then I'd know it would only run a max of 4 times, regardless of how many materials were in the forge. This slider could be implemented in all crafting of components, ie Carpentry
