some bugs I've seen with the recent, fun expansion release (iOS version):
1. First lightning: was mentioned above, but bears repeating. Can't space race it as US, and can't play it for ops as the USSR without lowering defcon, and sometimes can't even space race as USSR, and can't be headlined. So, it becomes an albatross that is almost impossible to discard for either side.
2. Don't wait for the translation: as USSR, there is no option to resolve event first. Is that a bug or by design?
Zero turn: when exiting the app and returning later during zero turn, the pop-up is gone, so no way to proceed. Workaround seems to be restarting iPad.
Alternate Europe scoring card: doesn't show crosshairs icon under Europe to show it has been scored.
Stanislav Petrov: card shows 2 ops but plays as 3 ops.
Kremlin Flu: icon sticks around after effects are removed, and even shows twice if used again in the game.
Hope this helps, I've been playing almost every day and it's a great game. The original release was flawless, so I'm sure the team will squash these bugs well.
