Changelog

Changed

• Structure generation is now permanently disabled in all void dimensions (Overworld one-block, void Nether, void End). Previously configurable via generateStructures (default true), this option has been removed entirely.
  • OneBlockChunkGenerator and VoidDimensionChunkGenerator now always construct with new DimensionStructuresSettings(false), hardcoding structures off regardless of config.
  • Old world-gen constructors that accepted a generateStructures boolean are kept for save-compatibility only — the flag is accepted but ignored, so existing worlds/configs still decode without crashing.
  • Reason: structure placement logic (height sampling, surface checks, stronghold ring search, modded structure preconditions) assumes normal terrain exists. In a void world these assumptions break in inconsistent, hard-to-track ways across different mods — strongholds partially generating, structures floating or sinking, silent placement failures. Disabling structures outright removes an entire class of these bugs.
  • End-specific content (obsidian spikes, exit podium, gateways, dragon fight) is unaffected — these are placed directly by dedicated handlers (EndPodiumHandler, EndGatewayHandler, DragonFogHandler) and VoidDimensionChunkGenerator#placeEndSpikes, not through the generic structure system.

Removed

• generateStructures config option (Void1BlockConfig). No replacement — behavior is now fixed.

Documentation

• Updated README to remove references to structure generation/preservation and reflect the new structure-free behavior.
