I can't take off because the launch is not active (Attach to catapult is not available in the action menu. Only the Launch.). I go near the hook and nothing. I can go further and i can go through the staff in front of me. I did a turn and try it again. It is same every time. I unable to take of with the catapult.
Maybe also helpful info:
Also the "Right Panel mode" is always available in the action menu, even if i'm on foot at the beginning of the mission.
