While working on the interior of a build on my creative world, I decided to decorate by using a painting.
Instead of cycling through the different kinds of paintings as I normally would, I would constantly get huge paintings, and nothing else. Despite trying, again and again, I found that it was impossible to get the smaller, more common paintings.

1). Go up to a wall (for me, this was a wall of around 5x3 blocks)
2). Place painting on wall.
3) Notice that the painting is one of the bigger pictures (for me, this is the painting with the two people duking it out using karate, a 4x2 painting.
4) Destroy and replace the painting to get a different one.
5) Notice that you constantly get the largest paintings, constantly. The smaller ones don't exist apparently. ಠ_ಠ;
