The Journey Planner should indicate which Yards you still need to add to the Planner.
Flag Yards that haven't Loaded before the Unload
e.g. SM Unload, SM Load -> MF Unload, MF Load -> SM Unload. If you don't have the last SM Unload in the planner, it should tell you (similar logic as #11 where only counts the Unload if it sees a Load first)
Relates to #11
