Muscle Memory

## 1.3.1

**Smelting counts every item, not every trip to the furnace.** Craft progress was a
flat 4 whether you took one ingot out or a stack of sixty-four, which is why the branch
felt impossible to level. The furnace fires its event once when the output slot is
emptied, however much was in it, and the mod was paying per event instead of per item.
Reported by user_ycyk8fq5c6h3ei62 - thank you.

The same mistake was in two Craft nodes, and both are fixed with it:

- **Smelter** rolls its chance once per item smelted rather than once per stack taken,
  so at three ranks a furnace load now yields around a fifth again as much instead of
  one extra ingot at best.
- **Apprentice** pays one experience per rank *per item*, where it used to pay a flat
  two per rank for the whole stack.

**Crafting is not affected.** It looks like the same bug from the outside, but the game
fires the crafting event once per craft - shift-clicking a stack of torches fires it
once per set of four - so the reward already follows the work done. It stays per craft
rather than per item on purpose: reversible recipes mean anything paid per crafted item
can be looped forever, which is the trap Bulk Work fell into in 1.2.0.
