42:32 First you accept the mission, then you mark the drop on the map, immediately after that you give them a vaccine, mission completed and then you can go to pick up the drop (if you crash or restart the game, the drop disappears). The difference is that these vaccines and the one you craft occupy a different slot😉 Sometimes the drop icon doesn't show it on the map, but when you move the cursor over it, it makes a sound. In any case should give/mark the drop on map before you give the vaccine to NPCs.
