SFML only draws some sprites - c++

Question

I'm having a strange problem where one sprite is loading however another isn't
Here is my main.cpp
window.draw(universe.getPlayer()->draw()); //Draw Player
std::list<AbstractBlock*>::const_iterator i;
std::list<AbstractBlock*>* values = universe.getLoadedBlocks();
for (i = values->begin(); i != values->end(); ++i){
window.draw((*i)->draw()); //Draw Blocks
}
window.display();
Here you can see the player drawing and all the blocks in the universe drawing. However, only the player draws and the blocks don't draw at all. I have made sure that the loop is actually working. However because draw() returns void I can't actually see if its working or not.
Here is the DirtBlock.cpp (I'm inheriting from AbstractBlock)
DirtBlock::DirtBlock(int x, int y, float rotation, b2World *world){
bodyDef.position.Set(x, y);
bodyDef.linearDamping = .03f;
bodyDef.type = b2_dynamicBody;
fixDef.density = .1f;
b2PolygonShape shape;
shape.SetAsBox(16, 16);
fixDef.shape = &shape;
body = world->CreateBody(&bodyDef);
body->CreateFixture(&fixDef);
texture.loadFromFile("Dirt.bmp");
sprite.setTexture(texture);
sprite.setOrigin(16, 16);
}
sf::Sprite DirtBlock::draw(){
sprite.setPosition(body->GetPosition().x, body->GetPosition().y);
return sprite;
}
Not everything is included, only the stuff that is involved with the drawing.
My Player class is very similar:
Player::Player(b2World *world){
texture.loadFromFile("player.bmp");
bodyDef.position.Set(10, 10);
bodyDef.type = b2_dynamicBody;
fixDef.density = .1f;
b2PolygonShape shape;
shape.SetAsBox(16, 16);
fixDef.shape = &shape;
body = world->CreateBody(&bodyDef);
body->CreateFixture(&fixDef);
body->SetLinearDamping(.03f);
sprite.setTexture(texture);
sprite.setOrigin(16, 16);
force = 10.f;
}
sf::Sprite Player::draw(){
sprite.setPosition(body->GetPosition().x, body->GetPosition().y);
sprite.setRotation(body->GetAngle() * (180 / b2_pi));
return sprite;
}
Since they are so similar why is one drawing and the other not? I have a feeling it might be because of my inheritance. I'm typically a Java programmer and I'm not 100% sure I did the inheritance correctly in C++. Should it be like this? (My DirtBlock.h)
class DirtBlock: public AbstractBlock
{
public:
DirtBlock();
DirtBlock(int x, int y, float rotation, b2World *world);
~DirtBlock();
virtual sf::Sprite draw();
virtual void destroy(b2World *world);
private:
sf::Sprite sprite;
};

I actually fixed it myself. It turned out to be a stupid mistake on my part but I might as well write and answer so if anyone else makes this mistake they may find this and it may fix their problem.
I didn't make the function draw in the AbstractBlock class virtual. Because of this, when I was calling draw for the DirtBlock, it was looking for the draw method in AbstractBlock that didn't have a virtual flag.
