Ensure starting PIE after editing character blueprint of a code based side scrollers

After editing character blueprint of a code based side scroller project, starting PIE will show the camera detached from the character and exiting PIE causes the project to crash.

NOTE:
This appears to be isolated to the Side Scroller template project. Tested third person template and rolling ball template without having the same problem

NOTE 2:
This crash did not occur for a blueprint based Side Scroller project.

Regression:
This is a regression. 4.10.4 Binary does NOT crash after editing BP followed by PIE.

NOTE 3:
This may be related to [Link Removed]

1. Open UE4 Editor
2. Create a new code project based on the Side Scroller template
3. Open SideScrollerCharacter BP
4. Compile
5. PIE (camera is not positioned correctly)

Result:
Ensure when PIE starts up

Expected:
PIE starts without ensure

Repro Rate:
3/3
