when throwing/putting crystals into a crucible that is already melting another material(BUT has none of the fluid in it and has slot open for the crystal) it will void the old material and melt the material of the new crystal that is put in
fluid hoppers will push/pull material from crucibles or other fluid hoppers without checking if the fluid is the same that it already has in the hopper voiding the pushed/pulled fluid
