I have razed a Mayan city at (55,50), but some tiles of the second city ring kept for some reason Maya as owner (even as I have 50%-66% of ownership!), and since I signed a peace treaty with the Mayans, my units are now stuck! This has been going now for several turns, though some of the sea tiles have lost their ownership after the first turn :
You gained more % of the tiles because of the battles, but the secound ring in your city has yet to be processed by culture produced in the city, I guess (getting it to level2). Also, the realistic culture spread prevents some tiles (like hills or forest) to be easily occupied by culture, even if culture level was achieved.
P.S. always have 4-5 storytellers in your attacking stack to avoid the X-turns anarchy status of city and get culture lvl 2 asap to get all tiles in the fat cross fast.
@all coders: could AI be taught to use storytellers in their attacking stacks?
EDIT: Ah yes I know what you mean now.... There are tiles around razed city remaining of the culture of razed city. It's a bug goining back some time, I have had it, too, once or twice.
