I play G+K and have noticed that when I have a stack of units in a city, the game will not sequence through all of them that have not been used before ending the turn.
For example, I have 8 stealth bombers in a city. Even though I have not indicated that I want get any of them to full health before using them, the game will routinely put up only 2 or 3 of the 8 for me to employ.
To get all eight up for use, I have to click on the city repeatedly and even then it can take quite a bit of clicking above and below the city name for those "hidden" stealth bombers to come up for me to use.
