Parent scripts are losing references to fields in their children when copied.

- "Parent0" gamobject has a parent script, and a gameobject "Child0" has a child script with some public field, e.g. int that is set to 5.
- In "Parent0"'s Parent script, child = "Child0"'s child script.
- Copy "Parent0" and rename to "Parent1", and rename "Child0" to "Child1"
- Copy "Parent1" and rename correspondingly to "Parent2" and "Child2". Notice that the public field in the Inspector in the "Parent2" is not initialized showing value 0. However, in "Child2" the value is correct.
