SharedObject deleted during update?

We just had an update to our app go live in the Apple App Store. Problem is it's wiping the save data in the SharedObject. I'm not sure of the culprit. We were using AIR 3.6, but had to update to get approved with iOS 7 for an update as the Sound.play()/microphone request bug was causing us to get rejected.

I've seen the bug people reported back at 3.5, but that wouldn't apply here. Were there any changes to Shared Object handling between 3.6 and 3.8 that might cause this? I know they made changes around iCloud backups... but I'm not sure if that would have affected anything.

I don't know what to do other than try to warn people not to update through the system. This didn't happen while testing through Test Flight, so I'm at a loss.

Thanks for any insights.
