Is anyone having this issue? Still in 1.09v

Does anyone have their city names randomly change, though they change back once you build something in the city?  It seems to be just a cosmetic bug,  The city colors always change to yellow, which I assume is the name of a neutral city.

If needbe tonight I can play a game and replicate this, though it takes a while for this to start happening, and it's happening more rarely in the later patches.
