Broken: version: 2.91.0, branch: master, commit date: 2020-11-25 08:34, hash: rB0f45cab862b8
Worked: (newest version of Blender that worked as expected)
Short description of error
VSE seems to delete blend files after opening and sometimes after saving.
Exact steps for others to reproduce the error
After opening a VSE .blend file containing large (4 hr) video files the .blend file is removed from the working directory.
Sometimes these .blend files are also deleted sometime after saving
On save and exit from Blender via the File --> Exit the .blend file is missing and must be recovered on the next session start
All files are in the same directory Blender should have adequate permissions.
