Hey I am stuck during mission 4, the one you show on the video here :

After receiving the medevac objective and landing to get the 4 passenger, I head to the medical carrier and as soon as I land I get the end of mission report with the objective failed.
I first thought it was timed and I was too slow but I tried lending near the bridge before the objective is triggered to save some time but I still get it failed everytime I touch down on the medical carrier.
