Hello,
apparently, the Furnace Smelt Speed configuration section does not scale properly. While the speed gets adjusted accordingly within lower smelt speeds, it eventually caps which leads to no noticable difference between example values of 50, 100 and 1000. All of them appear to be within the same time.
Additionally, when opening the UI of a furnace and clicking on any empty inventory or furnace slot, the selected slot gets deselected automatically, leading to a buggy feeling visual flicker as reported by some of my players.
