Just downloaded 0.9.08 (RC8) and re-added a torrent I was downloading earlier. It's definitely downloading to the same directory, but it appeared to start form scratch and not recognise that I'd downloaded some of the files already.
Known bug? (I didn't see it in the bug list)
Cannot resume torrent with RC8
Re: Cannot resume torrent with RC8
I have encountered the same problem. To fix this for the time being, I pause the torrent, and have it "Force Re-check". This resolves what was missing. This happens to me only when I had to restart using the power button, and might have some corruption.
