Andrew - Yes, that was my guess too.

It might be an idea to warn people in advance that rendering individual tracks with the .WAV command, in the way we've always done, now risks obliterating the SGU file - unless you've first saved the SGU with a different name, or renamed the rendered tracks.

Renaming files was the workaround I suggested might be needed - see my second post above.

As I suggested in my previous, I think this is maybe a more serious issue than the normal quirks of new releases. A DAW known to obliterate the file on occasion when hitting render would not last long.

Best - Andy
