ID: b7f1142c-a9b8-42be-a8f8-1e7322150928 I moved 599 emails from a local folder to a local archived folder (drag & drop). The archive parent folder showed 517 unread emails. As I was scrolling to find them, Thunderbird crashed. When I reopened firebird, all of the moved files are gone and dated 12/31/1969. Thunderbird will crash every time I click the link for "All Crash Reports" from the troubleshooting page.
