JFD, I removed the redundant mods and the CL Civs. I'm 200 turns into a really fun game and it looks like that might have done the trick, so thank you.
One thing that did happen was that I had the event pop which asks if you'd like to upgrade the city level for one of your cities, and when I chose to do so it did cause a crash. Unfortunately, I loaded and then kept on trucking, therefore I don't know if the logs that I have would cover that event. If you'd like to see them anyhow, I can post them.
And, for what it's worth, I would also cast a vote for the darkest brown citizen icon.
