Functions overriden from Parent BPs are not called in Child BPs when nativized

When nativization is enabled, functions in a child blueprint that were overriden from the parent are not called properly.

Regression?: Yes
This did not occur in 4.19

1. Create a new project based on the Third Person Template
2. Right-click the Third Person Character BP and create a Child blueprint
3. In both the Third Person Character BP and the Child, have them print out Parent and Child, respectively, on Tick
4. Place an instance of the Child in the level
5. In Project Settings > Packaging, enable Inclusive nativization
6. Package the project for Windows 64 bit
7. Launch the packaged game
   Result: The print string on the child does not fire, while the parent does
   Expected: Both the parent and child's print strings fire
