Ghost Physics Bug Still exists #43699

When parenting a rigid body object, to another rigid body, it leaves behind a "ghost" in the physics engine,
in some cases the ghost is impact-able,

I zipped my archive, because the python provided is a external module (it was provided to me this way)

https://drive.google.com/file/d/0B29hKf6-B52cSVNUSlp5cEVFb0U/view?usp=sharing

I can try and make a simple test file, but this video should illustrate the issue

Never mind the zip archive, I was able to reproduce just using logic.

A better description would be parenting the object and then moving it leaves the ghost,

I work around maybe un parent move re parent?

could moving a compound child update the compound parent?

This bug doesn't have the same cause that bug #41285. The issue in this case is related to that the children and the AABB compound box is not updated when children position is updated. The #41285 bug was related to that the children physics position was not taked into account when the compound was created

yeah, It was very confusing before, because I had both bugs at the exact same time.
