I have a custom tree. I can place it with the place command, and it generates in world gen. But when I try to grow the custom sapling it doesn't work. The sapling works with a vanilla tree grower, but not with my own tree grower. This is my sapling:

  public static final RegistryObject<Block> ABYSSAL_SAPLING = registerBlockAndItem("abyssal_sapling", () ->
            new AbyssalSaplingBlock(new AbyssalTreeGrower(), BlockBehaviour.Properties.copy(Blocks.OAK_SAPLING).color(MaterialColor.COLOR_CYAN)));

This is my configured features class:

public class ExtraConfiguredFeatures {
    public static final DeferredRegister<ConfiguredFeature<?, ?>> CONFIGURED_FEATURES =
            DeferredRegister.create(Registries.CONFIGURED_FEATURE, SculkyExtras.MOD_ID);

    public static final ResourceKey<ConfiguredFeature<?, ?>> ABYSSAL_TREE = createKey("abyssal_tree");
    public static final ResourceKey<ConfiguredFeature<?, ?>> ORE_DEEPSLATE = createKey("ore_deepslate");
    public static final ResourceKey<ConfiguredFeature<?, ?>> ORE_SCULK = createKey("ore_sculk");
    public static final ResourceKey<ConfiguredFeature<?, ?>> ORE_TUFF = createKey("ore_tuff");
    public static final ResourceKey<ConfiguredFeature<?, ?>> SCULK_LUSTRE_EXTRA = createKey("sculk_lustre_extra");
    public static final ResourceKey<ConfiguredFeature<?, ?>> SCULK_TENDRIL_PATCH = createKey("sculk_tendril_patch");
    public static final ResourceKey<ConfiguredFeature<?, ?>> SPRING_SCULK_OPEN = createKey("spring_sculk_open");

    public static ResourceKey<ConfiguredFeature<?, ?>> createKey(String name) {
        return ResourceKey.create(CONFIGURED_FEATURES.getRegistryKey(), new ResourceLocation(name));
    }

    public static void register(IEventBus eventBus) {
        CONFIGURED_FEATURES.register(eventBus);
    }
}

This is my custom tree grower class:

public class AbyssalTreeGrower extends AbstractTreeGrower {
    @Nullable
    @Override
    protected ResourceKey<ConfiguredFeature<?, ?>> getConfiguredFeature(@NotNull RandomSource randomSource, boolean largeHive) {
        return ExtraConfiguredFeatures.ABYSSAL_TREE;
    }
}

This is my configured feature

-- snip

public static ResourceKey<ConfiguredFeature<?, ?>> createKey(String name) {

    // no mod id passed to new ResourceLocation() as the namespace

    return ResourceKey.create(CONFIGURED_FEATURES.getRegistryKey(), new ResourceLocation(name));

}

Your ABYSSAL_TREE configured feature has the name minecraft:abyssal_tree ?

I changed new ResourceLocation(name) to new ResourceLocation(SculkyExtras.MOD_ID, name) and now it works. Thanks!
