Transmission

Argh!! Yea, looks like sometimes once you're at around or over 99.00% the only thing to do is keep resuming manually every time it errors out. Bummer!

Ah, one more scenario: If you've gotten to the point where you can't pause & restart the download without the error message (and so can't do the Verify Local Data) then pause the download, shut down and restart transmission, select the paused download in question and Verify.

Let me simplify it for everybody:
Go to "Transfers" on the drop down menu, and click on "Verify Local Data".
If it's not clickable, pause the download first and then do it. Wait for it to check all the data and then continue the download.
That's it!
This will make Transmission re-check the data it ...
