I've gotten this bug several times and I've finally made sure to take screenshots that illustrate what I'm talking about. As well if Stardock is interested I have a save game illustrating this bug.
The issue here is after I load a saved game it takes several turns for GNN to properly report to me when ships are getting built. In this example that I have 2 Constructors are slated to be built for the next turn. After the turn is complete GNN only reports 1 Constructor being completed. I verified that the other Constructor was completed but wasn't reported.
Sometimes it won't report anything, but if I continue playing for several turns it eventually seems to report ships accurately. This can be very frustrating when you have a fairly large empire and continue the game after being away from it for a few days. I only seem to encounter this bug from a loaded game.
As follows are the screenshots that illustrate what I mean graphically. I can provide the save game if requested to do so; however, it is 3.79MB large but I can rar it to 180KB for easy posting.
