I haven't worked on this for 2 days, so here's a cleaned code of how I left it.
I'm almost sure the problem resides in the main file, so other fils are here in case you want to test
Main :
#include <SFML/Graphics.hpp>
#include <SFML/System.hpp>
#include <SFML/Window.hpp>
#include "BackgroundTileMap.h"
#include <fstream>
#include <iostream>
#include <string>
int const TILESIZE = 32;

{

sf::RenderWindow referencePic(sf::VideoMode(512, 512), "Tilemap", sf::Style::Titlebar); //Not tied to our problem, it's a secondary windows
//window.setVerticalSyncEnabled(true); Didn't solve the probleme in any way so we don't care : I got rid of it
window.setFramerateLimit(60);
sf::View view(sf::FloatRect(0, 0, 160, 160));
view.setViewport(sf::FloatRect(0, 0, 1, 1));
std::string fileoutputname;
