ApacheAttackHelicopter

I am following these exact steps and have tried everything and cant get this to work! :( the bodies that I target for the rope to connect to don't connect to it they just fall to the ground as if nothing happened. is there any extra settings Im missing or do I need to connect the corpse at a specific spot to get them to attach? plz help I know Im a couple years late but I just dont get why this works flawlessly for everyone else and doesnt work for me
