That’s a Negative, Good Buddy

I admit to playing a video game or two when the time is right. My favorite type, for better or for worse, are those where I kill nasty goblins and amass magical items in a quest to save the world with a band of hearty adventurers. Hey -- we've all got our vices.

I was enjoying one such game recently when I stumbled upon a bug trying to sell those magical items. I hovered over a set of lightning arrows to check their selling price (970 gold), and I noticed a little oddity: there was a small tick mark where there shouldn't be. Hoping for a rendering error, I eagerly pressed "sell" and awaited my bounty. To my surprise, instead of money I received a message saying, "You cannot sell items worth less than one gold piece." And when I looked closer at that tick mark, it turned out to be what I feared. A negative.
