I have tried various senarios : SENARIO 1 : Start torrent, let it download a short while till it 99.5% completed, before allowing the problem to appear, I shut down utorrent. Forcing utorrent to save the file to the harddisk. Then re-start utorrent to resume downloading from 99.5%. SENARIO 2 : Start torrent, let it download till it is 99.7% completed .Clicked on the 'STOP' button to stop the download. Hopefully that makes it save the torrent to the harddisks. Re-start again. So far so good SENARIO 3: Start the torrent, let it download. Leave it to download and allow the error to occur. Do a force-recheck, then start the torrent again. It resumes instead of at 99.7%, it jumps back to 98.7% and resumes downloading from that point instead of 99.7%. This keeps happening and the download never completes. Upgraded to 25233. Problem is still there.
