I can see that i have found 'Find a blowtorch in warehouse'. But when I use the lift in the warehouse so will the 'Take the elevator' part not be green. To get in to 'research' room so do I need a card. I don't know where to find that and get forward in the mission. I have the game on steam.

the lift is above the canteen area

Have you reached the control deck in Para Ark yet?

Not yet. I found a door in the canteen aera where i need a card that i did not have. But I look more in the canteen area. I have checked the area before some round, but i have maybe miss that lift.
