Contact with Emmerich (Metal Gear Solid 5: The Phantom Pain)

Hello. There was such an incident in this task: when Sahelanthropus appeared, I took Emmerech and gave a tear for the map, as if the task was to run away and thought the helicopter would call on the way, but it was highlighted to me that the task was failed, I was returned to the free game and the contract was completed, but There is no Emmerich at the base, and you cannot replay it. Please tell me how to be? :(
