I didn't save at the time, unfortunately, and I don't know how to reproduce this, but in a couple points in my recent game, the narrator started talking about milestones that weren't happening.  For instance, a city with 10 (I think it was) attached territories when none of my cities were above 4.  He duplicated that a few turns later with an even higher number.  I'm pretty sure I was getting some incorrect district counts as well, but I never bothered to count to be sure.
