I played through another 4 turns and then checked... I didn't know that the AI only built one thing at a time based on how long it took to build. I believe that is what is happening. I didn't anticipate sending a saved game and have already moved on

I will check in my current game (I have it loaded at grad school so I can play during lectures that bore

) and send a save if it seems to be recurring. Thank you for the responses and the info.
