Does this exception mean some messages will be skipped?

Does it go back and try this section again, or does it skip some messages permanently?

That error can happen. If the tool continues to run, just let it continue. If it would miss some files, it would notice at the next run and download them anyways.

@fabianonline this was in the message downloading phase, before it started on media. It doesn't appear to go back and check if past messages were skipped (but I see it does perform that check for media).

Could this mean that some messages have been skipped and not downloaded?
