[ohwell]

torrents completes, on completion Qt rechecks the download and then goes to and checks the files, and then it starts downloading the SAME files - AGAIN and  AGAIN and  AGAIN and  AGAIN and  AGAIN, and never getting anywhere.  Does anyone know what and why this is happening.

   

Also:-
Downloaded files keep vanishing???  Files that I have downloaded previously, and completed, are not there anymore.  I have had downloads complete, then the next day, they are gone.  I have looked in the folders, sometimes the original files are still there, with FRESH downloads with the QBIT ext.  Other times they cannot be found.

   

My setup:-

QBitorrent v4.1.3,  OS, Windaz 10 Pro. 64 bit with 8 GB of DDR3 Ram

i'm having the same problem but with only one file, I've tested on 2 x pc file comp's > checks> moves to new folder > then disappears > restarts downloading again ..and at 86bg is a bloody pain , I've gotten to the point I've installed Utorrent on one of the 2 pc's to see what happens ..also no errors in the logs , it tells me the file is 100% , yet the above happens again and again i'm going nuts
