email form.[URGENT Bug Report] Project become corrupted
Please look at the screenshot below, I was only done some mesh editing and when I return to modelling view, I cannot click on any object (particularly the head area). When I reload the project, some of parts are gone. The problem persists even after restart.
I'm convinced that my project is corrupted because my old backup (thank god for auto-backup) showing just fine.

Please tell me where I can send my project file to for the staff to inspect the problem.
