Changelog

Version: 2.2.6
Date: 2026-02-22
  Performance:
    - Fixed 500ms hitch every 5 seconds: production/consumption buffers now pre-aggregate stats by (surface, quality) on insertion rather than accumulating thousands of individual timestamped records; flushBuffers() is now O(unique item×recipe×surface/quality combos) instead of O(total craft events over 300 ticks)

Version: 2.2.5
Date: 2026-02-22
  Bugfixes:
    - Fixed research consumption not being tracked after a mod config change: the initial entity enrollment (entity_count == 0 path) now builds force lab caches and seeds force_research_state for any force with research already in progress, so tracking starts immediately without waiting for on_research_started to fire

Version: 2.2.4
Date: 2026-02-22
  Bugfixes:
    - Fixed research technology sprite still overflowing at 256x256 despite layout size constraint; now uses a prototype image_style with stretch_image_to_widget_size=true so the image is scaled to 28x28, not just clipped

Version: 2.2.3
Date: 2026-02-22
  Bugfixes:
    - Fixed research technology sprite rendering at full size (256x256) in the production/consumption tables; sprite is now explicitly constrained to 28x28, matching the quality-icon branch and the 30px sprite column width

Version: 2.2.2
Date: 2026-02-22
  Bugfixes:
    - Fixed science pack consumption spike when switching to a technology that already has partial progress: on_research_started now seeds previous_progress from force.research_progress instead of 0, preventing the existing progress from being counted as a single-tick consumption event

Version: 2.2.1
Date: 2026-02-22
  Bugfixes:
    - Fixed crash in lab cache builder: LuaEntityPrototype does not expose researching_speed in Factorio 2.0; now uses (1 + entity.speed_bonus) as effective lab speed, which correctly weights same-type labs and is a safe approximation for mixed-type lab setups in mods

Version: 2.2.0
Date: 2026-02-21
  Features:
    - Track science pack consumption by research laboratories
    - Labs are registered in a dedicated partition (entities_lab) alongside assembling machines, furnaces, and mining drills
    - Research consumption is attributed per-lab using a speed-weighted cache (force_lab_cache) that accounts for per-lab module bonuses and researching speed
    - Consumption is split across surfaces proportionally to lab count per surface, supporting multi-surface Space Age play
    - Each technology gets a fake recipe "research-{tech.name}" with a technology icon and localised name in the UI
    - Cache rebuilds on on_research_started, lab placed, or lab removed; science packs appear in the consumption table under "Research <Tech Name>"

Version: 2.1.19
Date: 2026-02-21
  Bugfixes:
    - Guard against stale/invalid GUI element references (mainFrame, cons_table, prod_table, listbox_items) after mod reloads or player reconnects
    - Guard entity.mining_target.valid before accessing prototype chain in miners (prevents crashes when ore deposit becomes invalid)
    - onRemovedEntity now reads unit_number directly rather than passing the entity, which may be invalid by the time script_raised_destroy fires
    - Tick handler now guards against nil player from game.get_player and clears stale mainFrame references
    - Fix classic Lua bug in cleanupOldResults: table.remove inside ipairs was skipping entries; now iterates in reverse
    - Add nil guards on storage.consumers/producers before ipairs in all three production tracker update functions
    - Add nil guard in flushBuffers lambdas to handle unexpected missing storage.results entries
    - Add nil guards on prototype lookups in getDisplayNameAndSpriteForDynamicRecipe to handle mods being removed mid-save

Version: 2.1.17

Version: 2.1.10
Date: 2026-02-14
  Bugfixes:
    - Fixed consumption over-reporting for assembling machines and furnaces with productivity bonuses — bonus crafts from productivity don't consume inputs, so consumption is now divided by (1 + productivity_bonus)

Version: 2.1.9
Date: 2026-02-14
  Bugfixes:
    - Fixed infinite resource mining (crude oil, etc.) massively over-reporting production by not accounting for yield decay — output is now scaled by the resource's current yield factor

Version: 2.1.8
Date: 2026-02-14
  Bugfixes:
    - Fixed mining drill production tracking not accounting for mining productivity bonuses (from research, modules, etc.) — amounts are now multiplied by (1 + productivity_bonus) at tracking time

Version: 2.1.7
Date: 2026-02-14

    - /fi-verify-report now shows the latest background check results

Version: 2.1.4
Date: 2026-02-09
  Features:
    - Added verification console commands (/fi-verify-start, /fi-verify-report, /fi-verify-status) to compare mod tracking against Factorio's built-in production statistics
    - Verification report now sorts diverged items by severity, shows only top 10, and collapses untracked items into a summary count
