Extra info: Looks like the app had just gone to background when this happened. These are the "last second" breadcrumbs. Also, I can't figure out if the app will terminate fired because of the crash, or because the user closed the app.
Error Occurred 0ms before - App Will Terminate 0ms before - Orientation Changed (portrait) 0ms before - App Did Enter Background 2.00s before - Orientation Changed (portrait)
Lastly, the above happened during regular read/writes
