Editor Memory Leak due to scene change

Steps to Reproduce

  1. Play Scene X (Decently sized - Memory Around 3.3 K in Editor)
  2. Go to Scene Y (Like a diorama scene with high poly models)
  3. Go to Scene X again (Memory usage around 11k In editor)

Does UE4 trigger garbage collection during scene switches, if not how can I do it myself?

Note: This may not be a big deal in the executable however I am not able to work now without closing UE4 every time I cycle through scenes.
