If the user uses a Blueprint Interface in children Blueprints and then goes to the parent Blueprint and tries to implement the same Blueprint Interface in the parent Blueprint, the editor will crash.
Not a regression. Also occurs in 4.12.5 Release.
RESULTS:
Editor crashes with attached crash log.
EXPECTED:
Editor doesn't crash.
