[SOLVED]Saving and Loading

I am currently making a game where players can make buildings. However, when i was playing with saving and loading i stubbled accross a weird problem. Objects save fine but when they are loaded they sort of go invisible. However when i check the data by calling all the buildings in the system to check their positions and their names everything looks fine so yeah im kinda confused :confused: . One thing you might want to know before looking at the code, “buildings” is an Arraylist and takes three parameters, i.e. new Building(string, int, int);. Here is the code i use for saving and loading buildings:

public static void Save_Buildings() {
		try {

			// saving
			FileOutputStream saveFile = new FileOutputStream("saves/World_Data.sav");
			ObjectOutputStream save = new ObjectOutputStream(saveFile);

			save.writeObject(Object_Control.Buildings.size());
			
			for (int i = 0; i < Object_Control.Buildings.size(); i++) {
				save.writeObject(Object_Control.Buildings.get(i).name);
				save.writeObject(Object_Control.Buildings.get(i).x);
				save.writeObject(Object_Control.Buildings.get(i).y);
				}
			for (int i = 0; i < Object_Control.Buildings.size(); i++) {
				System.out.println(Object_Control.Buildings.get(i).name);
				System.out.println(Object_Control.Buildings.get(i).x);
				System.out.println(Object_Control.Buildings.get(i).y);
				}
			save.close();
			saveFile.close();
			
		} catch (Exception exc) {
			exc.printStackTrace();
		}
	}	
	public static void Load_Buildings() {
		try {
			FileInputStream saveFile = new FileInputStream("saves/World_Data.sav");
			ObjectInputStream save = new ObjectInputStream(saveFile);
			
			Object_Control.Buildings.clear();
			
			int AmountOfBuildings = (Integer)save.readObject();
			
			for (int i = 0; i < AmountOfBuildings; i++) {
				Object_Control.addBuilding(new Building("",0,0));
			}
			
			for (int i = 0; i < Object_Control.Buildings.size(); i++) {
				Object_Control.Buildings.get(i).name = (String) save.readObject();
				Object_Control.Buildings.get(i).x = (Integer) save.readObject();
				Object_Control.Buildings.get(i).y = (Integer) save.readObject();
				}
			
			for (int i = 0; i < Object_Control.Buildings.size(); i++) {
				System.out.println(Object_Control.Buildings.get(i).name);
				System.out.println(Object_Control.Buildings.get(i).x);
				System.out.println(Object_Control.Buildings.get(i).y);
				}
			save.close();
			saveFile.close();
			Menu.loading=false;
			
		} catch (Exception exc) {
			exc.printStackTrace();
		}
