You cannot expect things to work across versions. I always start a new game when I have downloaded an update. They change a lot of small stuff each version.
In case you failed to notice, I'm not really bothered by this, but found it amusing. Normally I reboot too, but I was in such an interesting position in that game I wanted to continue. Of course, being at war and all, my position just got more interesting. I like a good scrap.
