Not sure if this has been bought up before but the UI currently used in galciv4, which is presumably the exact same library being used in GalCiv3 (?), has a really hard time keeping up when the galaxy gets populated, to the point where it can't register a click properly and delays a full second before responding, a good reason to implement "repeat" options for all shipyard items.
It's not using Unity's IMGUI is it? that thing has a horrible cost for additional complexity and it shares the main thread so as your game goes up in processing your UI gets increasingly terrible responses (and the poor taxation on the minds of the devs who have to use it 
), there's some wild UI libs out there worth checking out, like PowerUI that'll consume 1ms and give you real JS/jQuery/callbacks/CSS selectors so web dev experience (which should be most of this earth at this point) can contribute to your project, throw in bootstrap or something, and away you go. I used it for a dev layer in a game and was blown away by how wonderful it was to use.
I'm assuming this is using Unity, in fact a fork of a GalCiv3 build, or is this all through UnrealEngine?
I hope it gets replaced, whatever it is, it's going to prevent any large games from being played to conclusion. With the size extensions to GalCiv3 this became painfully obvious as the engine just couldn't handle the larger game worlds and the UI would hang frequently for several seconds when trying to add things to build queues etc.
