Up until now, the event DropOffWagonsAtLocation would never acknowledge cars dropped off if the event was never activated. This is now possible so that location events that activate this event after the condition has been done will now trigger the event. The only issue is that the cars dropped off are not officially checked if they are indeed on the correct siding.
Note: This happens under MSTS so this is not a new feature.
