@Noisyfox, with your progress on building MOE SDK, do you have any clues how to nail down crashes like this? I can’t reproduce it locally and only getting crashlytics reports and these crashes are making the bulk of the app crashes in my app.
I’m guessing somewhere message is sent to selector which may not exist anymore, but without application code in this stack trace I can’t figure out how to debug this and could use any ideas.
