Have you updated the page of the cargo rocket yet?
Sorry, it kind of slipped my mind. I finally got a chance to put a good amount of time into my map which I don't get that often. I was cracked out for 4 days straight: digging, making, building, repeat.
But anyway...Just to make sure, are you asking if there is any sort of notification or indication your rocket has reached it's intended destination besides just going there and checking?
