I am having difficulty with finding the grappling arm interface. I am currently on the Avelina Dembo mission. I have purchased a grappling arm module, and have docked several times with cargo pods, both in this mission and freelance. I have searched all over the ship, on the bridge and elsewhere, even in the PAD, and cannot find any control or other interface that allows me to add the cargo pod to my ship or access its contents. Google searches have been fruitless as well. Would appreciate some assistance here.
