The general trade report does not seem to register sales from warehouses when the party cards are used (Potato party, Rum festival & Tobacco gathering).
If you buy these commodities in a port to be transferred to another port the purchase is registered as a negative value. This is correct. But, once transferred and a party card is used to sell them no profit is recorded. You then end up with an all time loss in the warehouses.
If the effect of other cards such as the East India Company etc is included in fleet profits surely the effect of party cards should be included too.
At present I am showing an all time loss of 18 million
