expanding on this, so i dont make unnecessary duplicates, iv encountered a number of issues in general with the inventory system with furnaces.

1. Furnaces will only accept 64 items if holding material in the mouse and clicking on the slot but will take whatever amount is there, if shift clicked.
2. Furnaces will only smelt up to 64 items at a time before stopping, this might be intended but in case its not just putting it here.
3. When shift clicking items from the furnace output back into the inventory, it not stack with whatever you might already have if its over 64 items and will make a new stack, then if you dont manually take that new stack and add it in the inventory page before you exit out, that new stack of items will be the only ones that are shown and the items that you had before are presumable voided.
4. when you have more item types then will fit in the typical inventory page, they overflow into the empty screen space below (i assume this is just a temp thing untill a proper expanding inventory screen or system can be developed).

5. Saving the world and then reloading it sets every item stack in any of the furnaces to 64 or less
