How to stop having a white square when using a sprite vector with SFML 2?

I'm trying to make a sprite vector but the first few elements always show a white square. The variables are contained in the TileRPG class to then be used in the main.cpp tile.cpp

void TileRPG::draw(int id, float x, float y, sf::RenderWindow& window) {
    m_sprite[id].setPosition(sf::Vector2f(x, y));
    window.draw(m_sprite[id]);
}


TileRPG::TileRPG() {
    std::ifstream file { "data/tileRPGList.rf" };
    std::string line{ "" }, access { "" };
    sf::Texture texture;
    sf::Sprite sprite;
    unsigned int i = 0;

    while (std::getline(file, line)) {
        m_texture.push_back(texture);
        m_sprite.push_back(sprite);
        access = "data/" + line;
        m_texture[i].loadFromFile(access);
        m_sprite[i].setTexture(m_texture[i]);
        i++;
    }
}

tile.hpp

class Tile {
protected:
    std::vector<sf::Texture> m_texture;
    std::vector<sf::Sprite> m_sprite;
};

class TileRPG : public Tile {
public:
    TileRPG();
    void draw(int id, float x, float y, sf::RenderWindow& window);
};
