Done the scenario twice now and each time I shut down all the controls and switch off the headlights and turn on the marker lights the game won't register that I've done this. So unable to change ends to finish the scenario.
I've had this on the 465 a few times. If the shutdown routine is stated in the task list then don't do them ahead of time, wait until it tells you to do them, mainly because you may move "ahead of the task" so it's waiting for you to do step one, when step 4 moves beyond this.
