I play mostly on mobile, and the stoke furnace button takes up nearly the entire Furnace location button. I tested, and trying to return to the furnace with a click on the stoke button instead brings up the confirmation prompt. This means that travelling back to the furnace just got a lot more difficult!
My suggestion is to either:
- Move the Stoke button somewhere else (like on the larger visualization)
- Only have the Stoke button pop up when you are currently at the furnace
