Changelog

Version: 2.1.3
Date: 2026-11-01
  Info:
    - Private-use standalone derivative of Reika's Geothermal 2.1.2 (see README.md and License.txt).
    - No longer requires Dragon Industries; the few helpers it used are built in.
    - Prototype names are unchanged, so placed wells/exchangers carry over from a save that used the original.
  Bugfixes:
    - Fixed the mod crashing on load (filtering called a Dragon Industries function it never loaded).
    - Updated for Factorio 2.1: recipe "categories", product "independent_probability".
    - High-pressure exchanger now targets the highest steam temperature allowed (500°C vanilla, 625°C if a mod such as Bob's raises it). 2.1 refused to load the original 625°C target.
    - Removing an exchanger now also removes its hidden intake. Before, the intake stayed behind forever, drawing 50 kW.
    - Rotating or flipping an exchanger now turns its back intake with it.
    - Heat wells built by robots from blueprints now work (they were never registered and never heated).
    - Fixed patch colour on AlienBiomes volcanic tiles (could crash with an unknown entity name).
    - Fixed patch sprites/lights not matching their temperature (random table order); cold -> hot now use the correct frames.
    - Fixed the east-south-east lava contact check on heat wells (it duplicated east-north-east).
    - Geothermal well now shows its own base graphic instead of the vanilla pumpjack base, and no longer flips into a pumpjack when mirrored.
    - Hidden heat-well reactor no longer has a 40 MW power draw inherited from the nuclear reactor.
    - Exchangers no longer show boiler fire.
    - Fixed missing/broken locale for biome rule options, setting descriptions and the quality tooltip.
  Changes:
    - Filtering recipes no longer accept productivity (it duplicated hot water and ore for free).
    - Patch lights can no longer be deconstructed into free small lamps.
    - Exchanger output fluidbox volume raised to 200 (2.1 derives max flow from volume).
    - Low-pressure exchanger can be upgraded to high-pressure with the upgrade planner / fast-replace.
    - Saves are scanned on load/mod change to re-register wells and exchangers and remove orphaned hidden helpers.
    - Changing spawn settings now applies to newly generated chunks.
    - Maraxsis / Tenebris settings only appear when those mods are installed.
    - Heat well quality tooltip is now relative to Normal (works with extra tiers such as Mythic).
    - Removed dead code (thermal wagon, unused turbine/extractor) and unused assets.
