Entityparent bug?

Graphics3D 640,480,32,0
box=CreateCube()
sp=CreateSprite("part.png")
EntityParent sp,box
FreeEntity box
EntityAlpha sp,0  ;<Entity does not exists!bug?normal?

edit:Maybe sp becomes part of the box and therefore deleting the box it will delete all the hierarchy?

Not a bug. FreeEntity also frees all children.

ops
Indeed :)
