That is, I first prohibit hiring any heroes in all cities, and then allow hiring heroes of that city's race in each city separately. Most likely, the loop is not correct; I think it is wrong to prohibit hiring all heroes. Perhaps there is a way to select individual values from the blockedTavern list for each case?
