[BUG] Culture lost when razing cities near your borders

[Diadem82]

Scenario:
- Enemy AI founds a city right next to the edges of my cultural borders.
- I declare war and raze the city.
- Razing takes one turn, so I own the city for one turn, including the tiles around it
- Next turn city is razed, all tiles around it return to neutral, including the ones I already had before the city was even founded.

Rather annoying, costs me a lot of money..

Please provide a savegame.

Ok. Two savegames, one (titled '7') just before declaring war. The second after taking the city and ending my turn. Just hit 'end turn' on the last save and wait and see the culture disappear.
