Prior to 4.0, shipyards and starbases updated once improved. To be more specific, a mining starbase would immediately update the mined amounts immediately after building a mining improvement. And a shipyard would immediately update "turns to build" after adjusting the sponsor list.
There is a trade-off. Also prior to 4.0, planets didn't properly reflect updated stats after rushing buildings, and now they do. I like that about the planets. I would also like to have the shipyards and starbases updating properly again.
Thanks.
