.Count and .List are often used together, so .Count should display the number of items that .List is listing.
But .List has an option .List(True|False) that indicates whether anything on or in the items in the list should also be listed.
.Count should have this same option so that can include all of the items that .List is listing.
Note also that .Count and .List should not be listing any objects that has Seen=False (Such as those inside of a locked container that the player has never seen inside of)
