I put this into the giant 117f bug thread, but no one seemed to notice. So I want to get confirmation from other players that they are seeing it and hopefully bring it to Firaxis' attention if it is proved true:
Take a stack of bombers. Have some of them go on bombard missions. Select one of the bombers that went on a mission. It will say that it has moved already. Then use the stack movement command, "j", with one of the bombers that didn't go on the mission. Now select a location to move the bombers. They all Rebase to the new position, even the ones that used their turn already bombarding. Very convenient, but I doubt it was intended this way.
