I have a huge building with strings of lights attached to one of the outer walls. I want to copy a large group with multiple 4m light strings to duplicate it in other spots on the wall. When i go into edit building mode, select multiple strings and duplicate them, the duplicates will not attach to the wall of the building. They come out in front, away from the wall. If i just select one 4m string, then no problem. Has anyone else seen this issue or have a solution? Thanks
