The market seems to have glitched out. Grain was trading at 0 gold for a good few minutes.
Edit: My apologies, I appear to have broken the market further. I managed to raise the price of grain to infinity, then I sold one grain for infinity gold.

EDIT: wool is going for 1.394975940552513e+27 gold!
EDIT2: The above seems to be causing the real-money trade to display "NaN" gold for $5 etc.
