I updated to 2.581 yesterday. It's a WIP but I didn't want to lose all the work if the machine should fry again.
Anyway, I checked the Lobby and the latest version is there 
I'll work on it some more today. I should be close to the final update. A-Bomb is done
For now. 
I currently have Moscow London and EUSA as German Targets and Tokyo Berlin and W GER as American. We can add more later. You can bomb anywhere but the Mushroom clouds won't show up unless in the above and only 1 per turn and 3 total.
That should be enough to decide the game
