When making ships, I create templates for each hull type, then upgrade them with the items I want, then save as "Frigate GA-1" to show me the hull type and weapon/armor and that it's the first iteration. So I am often naming ships the same thing I had before and saving over them. With the newest Beta (I didn't play much of the old beta though, so it might be in there) I am getting multiple versions of the "Frigate GA-1" showing up on every screen BUT the shipyard. So on the colony management screen, when I click on the starbase production column, I'm can choose between multiple versions of my like named ships. If I go into the shipyard and "obsolete" my design, all it's versions dissapear from the other screens. But as soon as I create another with the same name, all the old versions pop up again.
