At the very end of Mission 37 - Crossfire Chapter 10 - Houses united, when you use the trade lane to shorten the distance to the last waypoint and then approach this waypoint from the "wrong" direction (red line), the scripted cut scene apparently doesn't fire correctly. The ships just continue flying and never stop at the rendezvous point, and the cut scene never ends.
Flying directly to the waypoint works fine (green line).
