Variable Reset on Child in level

For a child instance inside of the level, the value of a parent int variable will reset if you add a new variable in the child and if there is a function in the parent that has the child as an output.

Regression:
This issue occurs in 4.13, 4.14, and the 4.15 binary builds

1. Create a new project (No template or starter content needed)
2. Create a new Actor class blueprint > Name it "Parent" > Open Parent
3. Add an Int Variable in Parent > Make it editable and exposed on spawn > Compile and save
4. Create a child based on Parent > Name it "Child" > Open Child
5. Add an Int Variable in Child > Make it editable and exposed on spawn > Compile and save
6. Add an instance of Child into the level > set the value of the child Int to 20 > set the value of the parent Int to 10 (Screenshot 1)
7. Create a new function in parent > add a new output whose type is Child > Compile and save (Screenshot 2)
8. In Child add a new variable

Result: The value of Parent Int resets for the Child in the level
Expected Result: The value of Parent Int stays the same for the Child in the level
