I'd say its pretty far feteched to "guess" that I saw the rice improved, then the city got destroyed and then I doctored up two screenshots to show a bug that doesn't in fact exist. Are you crazy?
The rice was not improved when I first saw it and cleared the blackness, and once it was later settled and improved I magically knew this since it updated in my map, its then when I sent the scout to check it out. I've since found this not to be isolated to rice, wine also has this problem.
Now this is a minor annoyance in a single player game, but when huts aren't updated, and notably not updated UNTIL I actually walk on them clearly some of the programmers were working to get an accurate game. But this is more than an annoyance in multiplayer games.
