FA bugfix for "dontdelete" (Patreon)

seems like VAM for some reason hangs up on missing audio files on some machines, doesn't on others. could be a performance thing - doesn't seem to happen on my machine.

take the latest 2.82.1 update if you are experiencing this issue and let me know if it fixes it for you, or if you see some new error. thank you.

either way let me know - ill figure out if that solves it for you or something else needs to be tweaked as well.
