Kerbal Space Program

Runway and launch pad cannot access saved ships to spawn until either building has been entered at least once.

In the mission builder, I am testing a mission, and have already created some craft from previous tests. Upon starting a new test where the first control is from a Kerbal outside of any building, returning to the Space Center and then selecting the run way to launch a vehicle right away results in all ships saying the parts are all locked. Then I entered the SPH, exited back to the Space Center, and selected the runway again. Now all the ships are available.
I think this is the result of when the test is done to see what parts are available. I think this should happen when ever you try to access the launch pad or runway as well as you might upgrade a building or technology and want to use an already saved craft right away but will be told the parts were still locked.
