I'm creating a game which stores a few variables using PlayerPrefs. It saves and loads the PlayerPrefs perfectly fine while testing in the editor, however when I build it to WebGL or Unity Web Player, both of them fail to save or load (I don't know which fails) and WebGL throws an exception on loading. Heres the c# script. Loading and saving are in their own procedures: loadData() and saveData()

public decimal money = 0;
public Text moneyTxt;

public Modal modal;

public AudioSource clickSFX;

private bool hasLoaded = false;

public Prog lemonadeStand;
public Prog newspaperDelivery;
public GameObject newspaperDeliveryBuy;
public Prog carWash;
public GameObject carWashBuy;

void Start () {
    askToLoad ();
}

// Update is called once per frame
void Update () {
    moneyTxt.text = "$" + money.ToString ("F2");

    if (Input.GetButtonDown ("Fire1")) {
        clickSFX.Play();
    }
}

void OnApplicationQuit() {
    if (hasLoaded) {
        saveData ();
    }
}

void saveData () {
    PlayerPrefs.SetString ("SaveMoney", money.ToString ());

    PlayerPrefs.SetFloat ("LemonadeStandMultiplier", lemonadeStand.multiplier);
    PlayerPrefs.SetFloat ("LemonadeStandUpgradeCost", lemonadeStand.upgradeCost);
    PlayerPrefs.SetInt ("LemonadeStandHired", lemonadeStand.hired ? 1 : 0);
    PlayerPrefs.SetFloat ("LemonadeStandPercentage", lemonadeStand.percentage);
    PlayerPrefs.SetFloat ("LemonadeStandTimeMultiplier", lemonadeStand.timeMultiplier);

    if (newspaperDelivery.transform.parent.gameObject.activeSelf) {
        PlayerPrefs.SetFloat ("NewspaperDeliveryMultiplier", newspaperDelivery.multiplier);
        PlayerPrefs.SetFloat ("NewspaperDeliveryUpgradeCost", newspaperDelivery.upgradeCost);
        PlayerPrefs.SetInt ("NewspaperDeliveryHired", newspaperDelivery.hired ? 1 : 0);
        PlayerPrefs.SetFloat ("NewspaperDeliveryPercentage", newspaperDelivery.percentage);
        PlayerPrefs.SetInt ("NewspaperDeliveryBought", newspaperDelivery.bought ? 1 : 0);
        PlayerPrefs.SetFloat ("NewspaperDeliveryTimeMultiplier", newspaperDelivery.timeMultiplier);
    } else {
        PlayerPrefs.SetInt ("NewspaperDeliveryBought", newspaperDelivery.bought ? 1 : 0);
    }

    if (carWash.transform.parent.gameObject.activeSelf) {
        PlayerPrefs.SetFloat ("CarWashMultiplier", carWash.multiplier);
        PlayerPrefs.SetFloat ("CarWashUpgradeCost", carWash.upgradeCost);
        PlayerPrefs.SetInt ("CarWashHired", carWash.hired ? 1 : 0);
        PlayerPrefs.SetFloat ("CarWashPercentage", carWash.percentage);
        PlayerPrefs.SetInt ("CarWashBought", carWash.bought ? 1 : 0);
        PlayerPrefs.SetFloat ("CarWashTimeMultiplier", carWash.timeMultiplier);
    } else {
        PlayerPrefs.SetInt ("CarWashBought", carWash.bought ? 1 : 0);
    }

    PlayerPrefs.Save ();
}

void loadData () {
    money = decimal.Parse(PlayerPrefs.GetString("SaveMoney"));

    lemonadeStand.multiplier = PlayerPrefs.GetFloat ("LemonadeStandMultiplier");
    lemonadeStand.upgradeCost = PlayerPrefs.GetFloat ("LemonadeStandUpgradeCost");
    lemonadeStand.hired = PlayerPrefs.GetInt ("LemonadeStandHired") == 1 ? true : false;
    if (lemonadeStand.hired) { lemonadeStand.enable(); lemonadeStand.percentage = PlayerPrefs.GetFloat ("LemonadeStandPercentage");}
    lemonadeStand.timeMultiplier = PlayerPrefs.GetFloat ("LemonadeStandTimeMultiplier");

    if (PlayerPrefs.GetInt ("NewspaperDeliveryBought") == 1) {
        newspaperDelivery.multiplier = PlayerPrefs.GetFloat ("NewspaperDeliveryMultiplier");
        newspaperDelivery.upgradeCost = PlayerPrefs.GetFloat ("NewspaperDeliveryUpgradeCost");
        newspaperDelivery.hired = PlayerPrefs.GetInt ("NewspaperDeliveryHired") == 1 ? true : false;
        if (newspaperDelivery.hired) {
            newspaperDelivery.enable ();
            newspaperDelivery.percentage = PlayerPrefs.GetFloat ("NewspaperDeliveryPercentage");

        newspaperDelivery.timeMultiplier = PlayerPrefs.GetFloat ("NewspaperDeliveryTimeMultiplier");
    }

    if (PlayerPrefs.GetInt ("CarWashBought") == 1) { 
        carWash.multiplier = PlayerPrefs.GetFloat ("CarWashMultiplier");
        carWash.upgradeCost = PlayerPrefs.GetFloat ("CarWashUpgradeCost");
        carWash.hired = PlayerPrefs.GetInt ("CarWashHired") == 1 ? true : false;
        if (carWash.hired) {
            carWash.enable ();
            carWash.percentage = PlayerPrefs.GetFloat ("CarWashPercentage");
        }

        carWashBuy.SetActive (false);

void askToLoad () {
