When a starbase on a resource point is destroyed or abandoned by a collapsed civilization, the resource point remains on the map but the tool-tip won't recognize it, and if you send a constructor there it doesn't seem to recognize the resource. It seems to be one of two different types of bug. Either the resource is destroyed with the starbase and the map doesn't graphically update to reflect this, or the resource is still there and cannot be utilized. Either way, a fix is in order.
Also, when in planet view if I select "Build ship" from the starport, if I change the type of ship being built and then select "back to planet" my changed build is lost and the starport build order reverts to whatever it was before. If I select "done" from the build ship menu, it keeps my changes but then drops all the way to the galaxy map. This is a real pain when cycling through planets to change builds when you go to war or end a war.
