The original OB was very unstable, the latest patch has improved stability tremendously, to the point where I very rarely see a CTD. As far as I'm aware the CTDs were the main thing the team were trying to eradicate up to and including the last patch.
The latest April Preview suggests that the upcoming update will contain more cosmetic improvements such as new units and descriptions, new traits and ancillaries etcetc.
I'm not on the team though so I dont really know :)
