This was a great mission, up until the supply probe drop...I was unable to acheive this goal despite numerous tries...no matter how close I got to the drop zone ( the closest I got was 600m away) it would register as a fail. I restarted the mission and tried again, I still got the same result. Am I reading the parameters of this mission correctly: land the probe less than 12000m away from the Hab?
