Cerys


Fulgora's moon of puzzles. Ancient wrecks embedded in thick ice can seemingly be repaired, including a colossal nuclear reactor that could transform the possibilities on the surface... if you can get it working. Cerys is a polished and complete planet mod that does not affect the vanilla game in any way, so is easy to include in existing saves.

Version: 0.9.26
Date: 2025-01-18
  Bugfixes:
    - Reinstated the tile cerys-empty-space. Although this tile does not have the desired properties, migrating it to empty-space was problematic because some bases relied on voiding items by dropping onto empty space with an inserter. cerys-empty-space is left as a legacy tile, whilst new saves will use cerys-empty-space-2.
Version: 0.9.25
Date: 2025-01-18
  Changes:
    - Space platform foundation can now be crafted on Cerys (but still cannot be placed.)
Version: 0.9.24

Version: 0.9.22
Date: 2025-01-18
  Changes:
    - Defrosting water puddles no longer destroy offshore pumps.
  Changes:
    - Adjusted the recipe for processing units from nitric acid to use the same amount of nitric acid as sulfuric acid used in the vanilla recipe.
  Bugfixes:
    - On new saves, fixed that space platform foundations could be placed around Cerys, which caused problems with asteroid gameplay and other areas. Since Factorio cannot handle migrating tiles that contain covering tiles which would now collide, old saves are migrated to have Cerys surrounded by the empty-space tile.
Version: 0.9.21
Date: 2025-01-18
  Changes:
    - Re-removed the limitation on requesting a maximum of 200 ice tiles to transition at once, since this will be unrelated to the reported bug. This fixes ice melting in an unusual order.
Version: 0.9.20
Date: 2025-01-18
  Changes:
    - Revert melting ice changes due to reports of bugs I can't reproduce.
Version: 0.9.19
Date: 2025-01-17

Date: 2025-01-15
  Changes:
    - Further performance improvement to solar wind.
    - Added a setting to control the spawn rate of solar wind particles, if all else fails on slower PCs. Note this performance concern is only relevant if a player is looking at the Cerys surface. Solar wind is already heavily optimized if Cerys is running with nobody looking at it.
Version: 0.9.13
Date: 2025-01-15
  Bugfixes:
    - Prevent circular dep with Cerys Lunaponics.
Version: 0.9.12

Version: 0.9.10
Date: 2025-01-14
  Changes:
    - Mixed oxide fuel cell reprocessing and crafting can both no longer be performed in Fulgoran cryogenic plants, as the number of module slots meant the loop was too positive.

  Changes:
    - Updated image for the mod portal.

Version: 0.9.2
Date: 2025-01-11
  Bugfixes:
    - Fixed the collision box of large methane icebergs.

Version: 0.9.0
Date: 2025-01-11
  Changes:

    - Charging rods now deflect solar wind particles at shorter range, making it easier to control their path.
    - Flipping the polarity of a charging rod no longer resets its energy to 0.
    - Positive charging rods no longer tend to violently scatter the solar wind.

Version: 0.8.0
Date: 2025-01-06
  Changes:
