5 months ago Figured out proper reproduction steps. v2.0.2.
Place down Ore Washing Machine Give it water and EU Place one Crushed Copper Ore inside Before it even finishes processing, directly swap the Crushed Copper Ore with something else, like Crushed Tin Ore. It will process the Crushed Tin Ore, but output the results of Crushed Copper Ore.
When placing the Ore Washing Plant, the first recipe completed after placing the block becomes locked into place regardless of the type of crushed ore put in. If the block is removed and replaced, the recipe is reset.
Example, if Crushed Copper Ore is the first completed, putting in Crushed Gold or or Crushed Tin Ore yields Purified Copper Ore and Tiny Piles of Copper Dust.
