This problem has bothered me for a while. I didn't know how to error check it.
But the best I can describe is: my torrent's content file loses data and goes to 99%
and produces a file missing error.
The only action done that I recall from any of these is copying a short text file
from the active and seeding torrent folder and then I see the file missing error with
the content file at 99%. I don't catch these in the moment because copying that
text file may happen days removed from creating the torrent.
