Hey edgesdarkly,
So this crash is related to one of our top crashes and we have been looking for repro steps, so thank you for providing such a detailed bug report.
Update: The 4.14.2 Hotfix release should resolve this crash as well as others similar or related. If you are still getting this crash after updating, please let us know and we will continue to track down the issue.
A good portion of these crashes are related to lower end machines using less RAM which is where the HUNG or REMOVED error message. We will continue to investigate this issue, and try to reproduce this crash internally to get a fix in place.
Let me know if you have additional questions.
Cheers,
