Russ, thanks for the report. Are you still able to reproduce this with a more recent build? Do you have more detailed steps to reproduce?

No, not since.  I realized the report was bit vague but, since they came in a cluster, thought it was worth reporting them.

> Do you have more detailed steps to reproduce?

No, as I mentioned, there was no specific action that triggered it, only the resultant outcome was the same.

Set WFM?

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.
