Strange Assimlation

[Entrex]

After playing a couple of games i decided that if i were attacking an enemy far away i would raze their major cities.

Now i'm playing a game where I started alone on a small continent. I was content on staying there and buidling my domestic improvements and soon i had tanks while they still had infantry. I decided to attack the main continent with all the other civs there. I took out kiev.. razed it.. then established a minor city.. for the aluminum so now i had modern armor. Now everyone is in a pact against me and I decided to raze each of their major cities and capitols and don't even bother with their smaller cities. I attacked Moscow, but decided against razing it.. it had only 8 pop but had 5 major wonders. It was in the heart of the continent and surrounded by Russian culture. I left one tank there so i don't lose my armies to assimilation. But the strangest thing happened.. or to say didn't happen. Moscow didn't revert.. instead after a couple of turns and then a sweet peace treaty I got a major score contributor and lots of wonders. Has this randomness of reverting happened?

WHat was RUssia's culture like? If yours was much higher (it should've been, after that 'domestic' talk then there's less chance of captured cities revolting.

The russians actually had a higher score then.. since they captured half of English lands. Their culture was same as mines.
