Hi, I noticed an exploit with the internal furnace bionic, you can consume torches as many times as you have charges on the torch. This essentially means crafting torches and using them to fuel your bionics power is too cost effective and easy in my opinion. Also I would like the internal furnace to be a little more hard to use as your main way to charge bionics, it seems to be best at it by far as it is now. Either you could increase the time it takes to consume items, or limit the amount you can consume at a certain time, so you would need to wait a little for the stuff to burn down and give power.
