Out of nowhere, my 7-ish minute project's ONE audio file stopped building peaks. I have versions of it cut and snippets placed around the project, but it all derives from the same audio file. I've tried other audio files too, and their peaks aren't building either. I tried deleting the sfk files but Vegas Pro 17 didn't even rebuild the peaks! Or make a new sfk file!. This is very troubling, and the peaks are essential to my project.
