Same problem. I exited the program, deleted the game and reloaded. Problem persists. I can raid (peacetime multiplayer) but I can't scout enemy bases or make war attacks. I get the message "error retrieving target player data." I can watch replays. We're in the middle of what looked like it might be a very close war, this is unfair to both sides. At the moment, we're ahead, but if we win, it might be because the best players on the other side were blocked from making attacks during the time the were available. Very unfair.
