Launch a vessel from the SPH or VAB then move it, once placed its state is remains PRELAUNCH.
I discovered this issue when working on Airpark in which the code remembers the vessels last state.
I would suggest setting to Landed or splashed (if over water) once the vessel is placed. I will be implementing a similar function in Airpark (If I can figure out how best to do it :) )
