If you assemble rocket with e.g. 2 side boosters (just to make issue visible), on launchpad rocket will be positioned rotated by 90 deg yaw.

I'll post screens tomorrow, but for now, pseudographics:

VAB, view from top:

    sea

 launchpad
    ||           - road VAB <-> Launch Pad
hangar door

 <>-{}-<>        - rocket with side boosters

Launch Pad, same view from top:

   sea

   / \ 
   \ /
    |
   { }           - rocket on launchpad
    |
   / \ 
   \ /

   ||            - road VAB <-> Launch Pad

   VAB

I am not sure is this really a bug, or it is intentional, but for me it is rather annoying.
If it is intentional, it should be configurable, or at least mentioned in wiki.
