Vendor: To limit the amount of mail that is sent to the vendor owner when items for sale on the vendor are moved to the vendor stockroom, the following rules have been implemented to determine whether mail is sent to the vendor owner when an item for sale on the vendor is moved to the vendor stockroom. 1) If the vendor owner withdraws the sale of an item, no mail is sent to the vendor owner. 2) If the item expired because no one has bought the item, mail is sent to the vendor owner. No more mail will be sent to the vendor owner for subsequent items on that particular vendor that expire because no one has bought the item, until the vendor owner accesses the vendor or the galaxy is restarted. The definition of "access" is the same as the definition of "access" currently used to determine the various vendor operational states.
