[1.13] Config getting reset due to it being set to a different value than default?


Recommended Posts

Not entirely sure why this is the case, as a config file's use case is for information that can be changed causes this warning and resets the value to default:

[09:55:03] [Client thread/WARN]: Configuration file .minecraft\config\controller-remap-client.toml is not correct. Correcting
[09:55:03] [Client thread/WARN]: Incorrect key Controller.sensitivity was corrected from 0.5371126755326987 to 1.0


    private ForgeConfigSpec.DoubleValue sensitivityConfig;

    private ForgeConfigSpec.ConfigValue<String> selectedMappingConfig;

public void build(ForgeConfigSpec.Builder builder) {

        sensitivityConfig = builder.comment("The sensitivity of the controller").defineInRange("sensitivity",1.0,-3.0,-3.0);

        selectedMappingConfig = builder.comment("The controller mapping that should be used").define("selectedmapping","xboxone");




        final IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus();
        modEventBus.addListener((ModConfig.ModConfigEvent event) -> {
            new RuntimeException("Got config " + event.getConfig() + " name " + event.getConfig().getModId() + ":" + event.getConfig().getFileName());
            final ModConfig config = event.getConfig();
            if (config.getSpec() == ConfigHandler.getCLIENT_SPEC()) {

            if(onFirstLoad != null) {
                onFirstLoad = null;

    private void load(ModConfig config) {
        this.modConfig = config;

        sensitivity = sensitivityConfig.get();


    public void reloadMappings() {
        File dir = new File(FMLPaths.CONFIGDIR.get().toFile(),"mappings");

        if(!dir.exists()) {

        String fileMapping = selectedMappingConfig.get();

        if(dir.isDirectory() && dir.listFiles() != null) {

            for (File file : Objects.requireNonNull(dir.listFiles())) {
                if(!FilenameUtils.isExtension(file.getName(),"mapping")) continue;

                if(FilenameUtils.removeExtension(file.getName()).equalsIgnoreCase("template")) continue;

                if(file.isDirectory()) continue;

                MappingConfig config = MappingConfig.loadConfig(file);

                if(FilenameUtils.removeExtension(file.getName()).equalsIgnoreCase(fileMapping)) {
                    selectedMapping = config;

The parameters of that overload of defineInRange are (path, defaultValue, min, max). You're passing 1.0 as the default value and -3.0 as both the minimum and maximum values.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.
