   Thanks!

   Still an issue on:
   Forge 1.20.1 47.4.10
   MineColonies - 1.1.1183-snapshot
   Structurize - 1.0.800

   I think I found where the bug is. In Structurize/src/main/java/com/ldtteam/structurize/storage/ServerStructurePackLoader.java , from what I understand, the code at line 83 is responsible for loading structure packs from the jar, but there is no code to check for the server config. Searching the ignoreSchematicsFromJar symbol confirms that this argument is never used anywhere in the code, besides when it is defined. Hope that helps!

   Did a bit more digging around. The same problem is also in Structurize/src/main/java/com/ldtteam/structurize/storage/ClientStructurePackLoader.java

   Also, these get run before the server configs have been parsed. Managed to fix that by doing in Structurize/src/main/java/com/ldtteam/structurize/Structurize.java:

   DistExecutor.unsafeRunWhenOn(Dist.CLIENT, () -> () -> {
       // 1. Keep the existing registrations
       Mod.EventBusSubscriber.Bus.FORGE.bus().get().register(ClientStructurePackLoader.class);
       Mod.EventBusSubscriber.Bus.FORGE.bus().get().register(ClientFutureProcessor.class);
       Mod.EventBusSubscriber.Bus.MOD.bus().get().register(ClientLifecycleSubscriber.class);
       Mod.EventBusSubscriber.Bus.FORGE.bus().get().register(ClientEventSubscriber.class);
   
       // 2. Add a listener for when the SERVER config arrives on the CLIENT
       IEventBus modBus = FMLJavaModLoadingContext.get().getModEventBus();
       modBus.addListener((ModConfigEvent.Loading event) -> {
           if (event.getConfig().getType() == ModConfig.Type.SERVER) {
               // This now fires only after the client has synced with the server/world
               ClientStructurePackLoader.onClientLoading();
           }
       });
   });
   
   IEventBus modBus = FMLJavaModLoadingContext.get().getModEventBus();
   
   modBus.addListener((ModConfigEvent.Loading event) -> {
       if (event.getConfig().getType() == ModConfig.Type.SERVER) {
           Log.getLogger().info("Structurize: Server config loaded. Initializing Structure Pack Loader.");
           ServerStructurePackLoader.onServerStarting();
       }
   });

   As far as I am aware this doesn't break anything, could be wrong. Also, the moment schematics get loaded from JARs, the setting becomes useless again. Basically, it only works if the world never had the option ignoreSchematicsFromJar set to false. I suspect it would be something to do with caching.
