BuildPatchServices app crash

Hi there!
BuildPatchServices crashing the application when retrieving app info from the just loaded manifest file after some time. Tested on UE 4.7.3. Steps to reproduce:

  1. Play project in editor
  2. Push button (Shift + F1 for show mouse cursor)
  3. Wait a lil about 30-40 seconds (on my machine) there will be a crash

Why?
Look at the test project TestProject.zip
