I have not played since; here are my log files.

I understand you can also do a crash dump report type thing… let me go try that now. EDIT: I only found some information pointing me back here, and this unique ID (hope that’s safe to share here): 4eef13aa-c4cc-11e4-8225-902b3455f36d. Hope that suffices.
