Sorry about that. It was getting old rotating Atlas on every build. Some Centaur and Titan parts are getting rotated as well so don't spend too much time rebuilding craft files right now. Please when you do rebuild them use fresh parts from the pallet, since craft files cache a lot of information and won't pickup a lot of not very obvious changes. It's so it flys in the correct attitude. Boosters arranged vertically, verniers on the side.
