Having an issue it sounds like a couple others are having, too. I have downloaded KK and the CustomPreLaunchChecks mods. When I start the game, the KK icon appears at the space center and in the VAB. That icon works, too. But out at the pad with a crewed vehicle with comms... I can't get the KK editor screen to appear when I press Ctrl+k to place objects.
