Situation
My non-Trader Duchess bought 25 bushels of food from her city. Some time later, her city has run out of food. However, game mechanics will not allow her to 'unload' the previously purchased food back into the city's warehouse through a newly posted buy order.
Error
The traders look at you funny as you try to sell them some of their own Food. It doesn't look as if they took it to be especially funny.
Why?
