Changelog

Version: 1.0.3
Date: 2026-08-15
  Bugfixes:
    - Reduced lag when copying large areas: blueprint patch only inspects
      module-capable entities and uses O(1) mapping lookup (no full-mapping scan).

Version: 1.0.2
Date: 2026-08-14
  Bugfixes:
    - Fixed ghost queue entries blocking re-placement after ghost expiry.
      Queue entries now store {entity, key} so invalid/expired ghosts clear
      ghost_queue_set immediately instead of leaving a sticky dedup flag until
      /abq-reset or full queue drain.
    - Recover from the "bots built the ghost before ABQ processed it" race.
      When that race hits, ABQ now clears the queue flag and attempts to adopt
      native item-request-proxies for module quality substitution, instead of
      only printing MISSED and requiring /abq-reset.
    - Fixed module quality intent lost when copying machines with many module
      slots / mixed module types. Canonical module requests (e.g. 3×legendary
      speed + 3×legendary efficiency + 2×legendary productivity) are now stored
      in entity tags (abq_modules) so blueprint/copy/paste preserves the original
      targets even while live proxies only show normal-quality substitutes.

Version: 1.0.1
Date: 2026-08-14
  Bugfixes:
    - Fixed quality recipes being lost on substitution.
      When a ghost with a quality recipe (e.g. rare personal batteries on an
      uncommon assembler) was substituted with a lower-quality entity, the
      recipe quality was reset to normal. Recipe quality is now captured and
      re-applied correctly via set_recipe(recipe, quality).
    - Fixed module requests when copying a mid-substitution machine.
      Copying/blueprinting a machine that still had ABQ substitute+upgrade
      proxies produced a ghost requesting mixed qualities (e.g. 1×normal +
      1×legendary) instead of the original intent (2×legendary). Blueprint
      setup now restores the full canonical module layout via event.mapping,
      and mixed-quality same-module requests on ghosts are consolidated to
      the highest quality target.

Version: 1.0.0
Date: 2026-06-29
  Features:
    - Updated for Factorio 2.1

Version: 0.9.4
Date: 2025-04-12
  Bugfixes:
    - Fixed ghosts from biter-killed buildings sometimes being missed by ABQ, and fixed a visual glitch where substitute ghosts could show a yellow upgrade arrow.

Version: 0.9.3
Date: 2025-03-30
  Bugfixes:
    - Fixed ghosts being silently abandoned when a blueprint demanded more items of a specific quality than the logistics network actually had available.

Version: 0.9.2
Date: 2025-03-29
  Bugfixes:
    - Fixed an issue where substitute modules were not delivered to entities in separate logistics networks.

Version: 0.9.1
Date: 2025-03-29
  Features:
    - Automatically fills blueprint ghosts with whatever quality is available in your logistics
      network, then upgrades each building as better items arrive.
    - Entities and modules are both handled — if legendary productivity modules aren't available,
      ABQ installs the best it can find and steps them up as better ones arrive.
    - All surfaces supported, including space platforms and surfaces without roboports.
    - Most settings adjustable in-game without restarting (Settings → Mod settings → Runtime).
    - Performance tuning settings for chunk scan speed and retry intervals.
