I'm sure this has been reported before, but every game I've played in 1.06 and 1.07 has a problem with both character portraits and city names/colors. Characters will change portraits seeming at random, and cities will display on the strategic map the names and colors of other cities, until I click on them, Neither of these are game-breaking, but they are certainly annoying.
Just something for the inevitable future patches. Keep up the good work!
