Solved YML Not saving correctly

I have a problem with saving and loading my playerconfigs.
In the console it says it saved the variable "coins" but it doesnt.
It saves all variables except "coins". Variable "coins" is type long.

My Code

Code (Java):

import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.configuration.file.YamlConfiguration;
import org.bukkit.entity.Player;

import java.io.File;
import java.io.IOException;
import java.util.HashMap;
import java.util.UUID;

public class PlayerConfigManager {

    HashMap<UUID, HashMap<String, Object>> values;

    public PlayerConfigManager() {

        values = new HashMap<>();

    }

    public HashMap<String, Object> getValues(Player player) {
        createIfNotExist(player.getUniqueId());
        return values.get(player.getUniqueId());
    }

    public HashMap<String, Object> getValues(UUID uniqueId) {
        createIfNotExist(uniqueId);
        return values.get(uniqueId);
    }

    public HashMap<UUID, HashMap<String, Object>> getValues() {
        return values;
    }

    public void createConfig(UUID uuid) {

        values.put(uuid, new HashMap<>());

    }

    public void createIfNotExist(UUID uuid) {

        if (!values.containsKey(uuid)) {

            createConfig(uuid);

        }

    }

    public PlayerConfigManager load() {

        for (File file : new File("plugins/RayNight/Playerdata/").listFiles()) {

            if (file.isFile()) {

                FileConfiguration cfg = YamlConfiguration.loadConfiguration(file);
                UUID uuid = UUID.fromString(file.getName());
                values.put(uuid, new HashMap<>());

                cfg.getConfigurationSection("").getKeys(true).forEach(e -> {

                    values.get(uuid).put(e, cfg.get(e));
                    System.out.println(
                            "Loading " + e + " " +
                                    "| Value=" + cfg.get(e).toString() + " for " +
                                    uuid.toString());

                });

            }

        }

        return this;

    }

    public void saveAll() {

        for (UUID uuid : values.keySet()) {

            File file = new File("plugins/RayNight/Playerdata/" + uuid.toString());
            YamlConfiguration cfg = YamlConfiguration.loadConfiguration(file);
            for (String e : values.get(uuid).keySet()) {
                System.out.println("Saving " + e + " | Value=" + values.get(uuid).get(e).toString() + " for " + uuid.toString());
                cfg.set(e, values.get(uuid).get(e));

            }

            try {
                cfg.save(file);
            } catch (IOException e1) {
                e1.printStackTrace();
            }

        }

    }

Config

Code (YAML):

enderchest:
  pages: 1
  page:
    '0': []
stats:
  deaths: 0
  money: 1000
  kills: 0
elo: 0
homes: []
perk:
  no_hunger: false
  strength: false
  speed: false
  fire_resistenz: false
  jump_boost: true
 

 

I do initialize it in my Main and "coins" is set right.

Code (Text):

RayNight.playerConfigManager = new PlayerConfigManager().load()

Im also getting it as Long in my PlayerConfig.

Its just not saving the long

 

Coins is set:

Code (Text):

new PlayerConfig(player).setLong("stats.money", money);
// PlayerConfig just gets the values from the hashmap for the uuid

 

It resets completely now
