this is a really weird bug i found. if you build a box with heavy steel and connect every point in the box to every other point in the box, when you go to simulate it the box explodes very violently. the one i have for download is a smaller box and explodes very rapidly. if you connect a couple of them together the explosion slows down and is very spectacular.
