mp3gainexpress deletes mp3s or they become unplayable

[joni71]

unfortunately i discovered only days after:

sometimes let say "1 every 30 songs" the song disappears or is unplayable

so now i duplicate the folders before apply app "treatment" and then i check if some song/s is missing

This is not helpful. The app literally warns you that this could happen the first time you run it and will continue to warn you unless you check the box to never warn you again.

You have provided no information other than it happens. There have been a few random reasons discovered for this behavior over the years and all of the ones where I was actually provided enough information to get it to happen myself have been fixed. Just telling me it happens does not help me fix a problem because it works fine for everything I have used it on.
