Digi greetings. Getting this message but I don't understand what I'm doing wrong. I detached a battery from my base. Lifted it via a landing gear attached to my little welder ship . Placed a weld pad on the bottom of the battery , a weld pad on the floor of my base several blocks away. When I fly the battery to within weldpad range I get the alignment messages but then this message. I've tried moving the pads to the back of the battery and then a wall on my base. Same error. The base is under ground. Any pointers. ?
