I had a sequence open among others I was working on. I finished the work on the others and went to that one to grab its content to place all the separate ones in the same timeline & its gone.
The bin I created the sequence out of is also gone, all the video files in it and named bin have disappeared.
Definitely didn't delete it or close it. More worryingly I went back through my auto-saves/ restores to a time I EXPORTED THAT SEQUENCE AT earlier today and when it completed its restoration..nothing
The sequence has ghosted itself. All the work on it is gone & the autosave within 10 minutes of me exporting that sequence comes up with nothing. (note: the auto-save prior to the export also has nothing) it's like it never existed.
