Changelog

Version: 0.9.2
Date: 2026-11-04
  Changes:
    - Ore patches are kept whole far more often: the shore can go out between nearby nests to take a patch in, or step inside the smallest island to leave it out.
    - Where the shore can't go round an ore patch either way, the water there narrows to 4 tiles instead of cutting the ore.
    - Peaceful is read from the planet itself, so Peaceful Planets' per-planet modes are respected.
  Bugfixes:
    - Walkable shallow water and mud in the way of the ring are now painted over, so they can't leave a bridge.
Version: 0.9.0
Date: 2026-11-03
  Info:
    - First release, for Factorio 2.1.
  Features:
    - At the start of a new game, loads land until the enemy nests round your start show where the island can end, then paints a ring of water just inside them.
    - The island is an oval that follows the nests, with a varied shoreline and water never narrower than 4 tiles.
    - Nests and worms too close to the start are removed first, so the island is never smaller than the setting.
    - Ore patches are kept on the island wherever the nests allow.
    - Settings: smallest and largest island, gap to the nearest nest, water width and shape variance.
    - No island if enemies are off or peaceful, or when the mod is added to a game under way.
