Child game objects in prefabs appear in the wrong positions when run from the launcher

[BraveSirAndrew]

Steps to reproduce:

Create a game object and attach a default sprite renderer (any visual component will do for this but this is the easiest). Position the object at 100, 100, 0.
Create a child game object of the first object and attach a sprite renderer to it also.
Move the child to absolute position 200, 200, 0.
Create a prefab from the objects.
Save the scene and run it from the launcher.
The child game object will appear at the wrong position, exactly on top of the parent object.
