I was going for some extra medals on the missions and noticed a problem on Tutorial #10 - Helicopter take off & landing mission. The mission is simple, you have to fly through five gates and land. But, after you complete this goal the voiceover says if you complete an addtitional four landings on certain helipads you will receive a bonus medal. The problem is that after the first additional helipad the throttle cuts and you cannot take off for the next one. Anyone else have this problem?
