I have my game set up so it saves my custom scene name labels as well as the time and date, but I want these to be translatable too. I have my custom handler set like this:

using System;
using System.Reflection;
using UnityEngine;
using UnityEngine.SceneManagement;
using SceneM = UnityEngine.SceneManagement.SceneManager;

namespace AC
{
    public class CustomSaveFileHandler_Timestamped : SaveFileHandler_SystemFile
    {
        private const string LogPrefix = "[CustomSaveFileHandler_Timestamped]";

        public override void Save(SaveFile saveFile, string dataString, Action<bool> callback)
        {
            if (saveFile == null)
            {
                ACDebug.LogWarning($"{LogPrefix} Save called with null SaveFile.");
                base.Save(saveFile, dataString, callback);
                return;
            }

            string rawScene = SceneM.GetActiveScene().name;

            int lang = GetCurrentLanguageIndex_Robust();
            ACDebug.Log($"{LogPrefix} Language index at save-time = {lang}");

            string friendlyScene = GetFriendlySceneName(rawScene, lang);

            string timeStamp = DateTime.Now.ToString("dd/MM/yyyy HH:mm");
            saveFile.label = $"{friendlyScene}\n[{timeStamp}]";

            ACDebug.Log($"{LogPrefix} Saving saveID {saveFile.saveID} with label:\n\"{saveFile.label}\"");

            base.Save(saveFile, dataString, success =>
            {
                ACDebug.Log($"{LogPrefix} Save finished for ID {saveFile.saveID} (success={success})");
                callback?.Invoke(success);
            });
        }

        // --------------------------------------------------------------------
        // LANGUAGE DETECTION (AC 1.85.5 safe + robust fallbacks)
        // Your setup (per screenshot):
        // 0 = English (Original)
        // 1 = German
        // 2 = Spanish
        // --------------------------------------------------------------------

        private int GetCurrentLanguageIndex_Robust()
        {
            // 1) Preferred: static Options.GetLanguage()
            try
            {
                return Options.GetLanguage();
            }
            catch { /* ignore */ }

            // 2) Fallback: try instance KickStarter.options.GetLanguage() (some setups)
            try
            {
                if (KickStarter.options != null)
                {
                    MethodInfo mi = KickStarter.options.GetType().GetMethod("GetLanguage", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);
                    if (mi != null && mi.ReturnType == typeof(int))
                    {
                        return (int)mi.Invoke(KickStarter.options, null);
                    }
                }
            }
            catch { /* ignore */ }

            // 3) Fallback: look for optionsData.language (common in AC)
            try
            {
                if (KickStarter.options != null)
                {
                    object optionsData = GetMemberValue(KickStarter.options, "optionsData");
                    if (optionsData != null)
                    {
                        object langObj = GetMemberValue(optionsData, "language");
                        if (langObj is int i) return i;
                    }
                }
            }
            catch { /* ignore */ }

            // 4) Fallback: look for language-ish fields on SpeechManager (names vary by version)
            try
            {
                if (KickStarter.speechManager != null)
                {
                    // Try a few likely member names without hardcoding AC version-specific APIs
                    string[] candidates = { "language", "currentLanguage", "selectedLanguage", "gameLanguage", "speechLanguage" };
                    foreach (string name in candidates)
                    {
                        object val = GetMemberValue(KickStarter.speechManager, name);
                        if (val is int i) return i;
                    }
                }
            }
            catch { /* ignore */ }

            // Default to original language
            return 0;
        }

        private object GetMemberValue(object obj, string memberName)
        {
            if (obj == null) return null;

            Type t = obj.GetType();

            // Property
            PropertyInfo pi = t.GetProperty(memberName, BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);
            if (pi != null) return pi.GetValue(obj, null);

            // Field
            FieldInfo fi = t.GetField(memberName, BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);
            if (fi != null) return fi.GetValue(obj);

            return null;
        }

        // --------------------------------------------------------------------
        // TRANSLATION
        // German first, then Spanish, else English (fallback)
        // --------------------------------------------------------------------

        private string GetFriendlySceneName(string raw, int lang)
        {
            if (lang == 1) return GetGermanSceneName(raw);   // German
            if (lang == 2) return GetSpanishSceneName(raw);  // Spanish
            return GetEnglishSceneName(raw);                 // English / fallback
        }

        private string GetEnglishSceneName(string raw)
        {
            switch (raw)
            {
                case "MeMeBedroom": return "The Bedroom";
                case "MeMeUpstairs": return "The Balcony";
                case "MeMeBasement": return "The Basement";
                default: return raw;
            }
        }

        private string GetSpanishSceneName(string raw)
        {
            switch (raw)
            {
                case "MeMeBedroom": return "El Dormitorio";
                case "MeMeUpstairs": return "El Balcón";
                case "MeMeBasement": return "El Sótano";
                default: return raw;
            }
        }

        private string GetGermanSceneName(string raw)
        {
            switch (raw)
            {
                case "MeMeBedroom": return "Das Schlafzimmer";
                case "MeMeUpstairs": return "Der Balkon";
                case "MeMeBasement": return "Der Keller";
                default: return raw;
            }
        }
    }
}

Which works, BUT doesn't work if I change the langauge in game, any ideas how to fix this? THANKS
