Child BPs created from Parent BPs that include nodes attached to the Event BeginPlay, Event ActorBeginOverlap, or Event Tick nodes include a Parent call in the Event Graph by default. This is inconsistent with Child BPs created before the nodes existed in the Parent, which do not show the Parent call after recompiling.
Reproduced in 4.7.6 binary and Main (//depot/UE4/Promotable-CL-2513846).
1. Open any project
2. Create a new Actor Blueprint, "ParentBP"
3. Add a Print String to Event Begin Play
4. Right-click ParentBP in the Content Browser and select Create Blueprint Based on This
Event Begin Play has a Parent: Begin Play call to the Parent BP.
