So, I was playing derivative clicker that someone posted. I realized you can sell things by saying you want to buy -1 of them at once. I was wondering what would happen if you sold something that you had none of... You can sell it, get -1 of it, and get money for selling it. I decided to sell a nonexistant Georg Riemann and got a lot of money for it. I started buying other stuff, then realized that because I had -1 Georg Riemann, I started getting negative Kurt Godels (I don't feel like getting the special o...), which ended with negative mathematicians, which ended with my tick length being NaN. The game interpreted that as 0 or something, and was constantly updating, giving me a lot of money and proofs. But I couldn't buy anything... I had to restart...
