Here is one more possible bug with changing location of downloaded files. Example: I'm downloading directory aaa with two files: file1 and file2. If I choose target dir C:\download then it will be C:\download\aaa\ I'm changing it to C:\download (so I want to get C:\download\file1 and C:\download\file2). Start download, it is finished. Everything is OK on this stage. Then stop, physically move file1 and file2 into C:\download\old\, LMB->Advanced->Set Download Location... and choosing dir C:\download\old\, start. Voila, it can not find files on HDD. I think that it still looks into C:\download\ instead of C:\download\old\. Workaround: open Files tab, LMB on file1 -> the last item in menu (should be something like "change location" or "re-locate"), explicitly choose C:\download\old\ directory. Repeat the same for file2. Hope this was clear enough. If no - let me know.
