I have a question. I noticed that when I finish upgrading a ship design and I already have ships of that older design on the map, A ship upgrade screen comes up after I hit save un the Shipyard. However it does not have an entry for my upgraded design on the list. Is that a bug, or am I missing something? As it stands I have to go and select the ship that needs upgrading then update it.
If I understand what you are saying, you are upgrading an EXISTING design that has ships on the map and saving that design under the same name, but not updating the whole class of ships at that time.
If this is the case then, no, not a bug. If you update a ship design with the same name, it will only show the #'s for ships of that upgraded design, the older versions will not show up in the shipyard at all. The solution is to either upgrade the entire class of ships when you save the design (a checkbox in the upper left of the save screen) which can be VERY expensive, or to use a different name. I usually use a naming scheme that involves the ships name, like SHARK and then add an identifier to the end like A,B,C OR 1,2,3 or such like. So you end up with SHARK A, SHARK B, ETC.
