Actor with physics gets detached from parent

I have a parent empty actor and a child object (actor) , and when i enable physics on the child it gets detached on start. I know this is by design but i DO want the child to move with the parent, so how do i disable this “by design” feature (or bypass it)?

This is not possible yet. UE4 only supports physics on, for the root mesh. If you want to have it enabled on the child, you have to create another BP for that child and make it root and try to move the second BP using the transform of the first BP. No need to mention that you must communicate between the two BPs of course.
