Re-enables quality modules for asteroid reprocessing in Crushers, restoring the Factorio 2.0 behavior that 2.1 removed. Also stops 2.0 saves from losing the quality modules already installed in crushers.

Crusher Quality Again

Factorio mod · factorio_version 2.1 · requires Space Age and Quality.

Re-enables quality modules for the asteroid reprocessing recipes of the
Crusher (assembler), restoring the behaviour Factorio 2.0 had.

Why this is needed

Factorio 2.1 gates recipe quality with the per-recipe boolean allow_quality
and sets it to false on the three reprocessing recipes:

• metallic-asteroid-reprocessing
• carbonic-asteroid-reprocessing
• oxide-asteroid-reprocessing

While a crafter runs a recipe with allow_quality = false the game removes
quality modules from it. When a 2.0 save is loaded in 2.1 those modules are
deleted outright during migration; they are not moved to an overflow
inventory, which is why upgrading silently destroyed quality modules that
players had built up over many hours.

This mod sets allow_quality = true on every recipe whose name contains
reprocessing, so reprocessing recipes added by other mods are covered too.

Behaviour

Installed recipes keep their other restrictions
(allow_productivity = false, allow_decomposition = false) and the recipes
stay otherwise identical, so only quality is restored.

factorio-current.log records what was changed:

Script @__crusher-quality-again__/data-updates.lua:56: [Crusher Quality Again]
allow_quality re-enabled on: carbonic-asteroid-reprocessing,
metallic-asteroid-reprocessing, oxide-asteroid-reprocessing

Compatibility

• Runs in data-updates, so recipes modified by other mods' data.lua are
  seen; a mod that sets allow_quality = false in data-final-fixes keeps its
  choice, which is correct load-order behavior.
• The crusher itself is not restricted in 2.1 (allowed_effects already lists
  quality). If another mod trims that list, this mod puts quality back.
• Saves can be downgraded by removing the mod; quality modules will then be
  removed from crushers running reprocessing recipes again.

Recovering lost modules

Modules deleted while migrating a 2.0 save into 2.1 are gone from that save and
cannot be restored by this mod, which only prevents further loss. Either load a
save written before the first 2.1 load with this mod active, or craft new
quality modules.
