Method ufoReachedWaypoint

src/Savegame/AlienMission.cpp:360–484

* This function is called when one of the mission's UFOs arrives at it's current destination. * It takes care of sending the UFO to the next waypoint, landing UFOs and * marking them for removal as required. It must set the game data in a way that the rest of the code * understands what to do. * @param ufo The UFO that reached it's waypoint. * @param engine The game engine, required to get ac

 * @param globe The earth globe, required to get access to land checks.
