I am midway through a gigantic galaxy and when I get a new technology that gives me a new planetary improvement that requires upgrading old ones. On some planets I will have five of the same improvement upgrading from the same improvement and I will have three differing upgrade times and costs to buy the exact same upgrade. I have reported this problem in previous builds and have heard no comment from Stardock whatsoever.
Scincerely,
Scintor
