the game will still fail to save Highlights in MP4
Oh! I didn't realize the issue was format specific.
I had the format setting on Auto. That defaults to MP4 now apparently, not sure what it defaulted to back then.
But I have just confirmed that I can successfully save highlights as WEBM! \o/ Thank you very much for this critical piece of information!
Meanwhile I created a ticket yesterday about the failure to save (bug 45862), I'm editing that now to reflect that it's for MP4 only.
