Also sometimes it crashes with

\ Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM _maskView]:

Could it be the case that the MRProgressOverlayView is not retained properly and is removed from the view hierarchy?

I was able at least once to reproduce this issue, but not constantly. This won't appear with the 0.8.0 release as new iOS 8 APIs are not used there. Thanks for your feedback. If something like this happens again for you, please feel free to create a new issue.
