Hi there, fantastic mod.
Just a minor bug - when launching ksp the trajectory will not display on the first flight. The mod loads ok, I can set a target and the green cross appears, but the red line / cross doesn't show (the "display trajectory" option is definitely enabled). The trajectory always displays fine on subsequent flights or by doing a quick save/load.
Easiest to reproduce by launching ksp and loading the dynawing re-entry or powered landing scenario.
KSP 1.2.2.1622, Trajectories 1.6.6
