Am I missing some UI function that allows me to idle a colony? I cannot go to the next turn until I tell it to do something when there are open tiles and nothing in the queue. In GalCiv2 it was sometimes prudent to idle a colony's social production while tiles were open in order to either a) put those resources toward military production, or
not incur maintenance costs until I could afford it.
Maybe these reasons don't make sense in GalCiv3. And yes I can put the Manufacturing to 0, but I still have to queue something.
