Android App appears to close when using a combination of nav mesh volumes, async loading and Gear VR.
Result: App closes once the sublevel containing the nav mesh is loaded
Expected: The level would be loaded and the app would continue to run
Also reproduces on Windows if the project has this settings in DefaultEngine.ini
