Steps to reproduce (a sample project is attached to the UDN):
Expected:
Both BeginOverlap and EndOverlap events are notified.
Actual (UE 4.27.2):
Only BeginOverlap event is notified, EndOverlap is not notified.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-171173 in the post.
