Reverted the game to the February 4th build.

This will result in another 1GB patch for those who downloaded the upgrade already yesterday. (For people who didn't download that, there should be no change at all). This patch isn't anything new, it is just undoing the difference between the Feb 11th version and the Feb 4th version. We apologize for putting yet another big patch up, but a number of people are reporting problems with savegames disappearing, and until we work this out we don't want to keep making problems. So, please be sure your copy of the game is updated before running. If you have a problem with your savegame not loading, pop into the tech support forum and we will see what we can do.
