"Done" percentage has reset to zero

[porphyry5]

I have been downloading a file the last 2 days, got to 87.2%, then stalled again.  Now I look at qBittorrent's panel again and see the % Done is now zero, as if I'd never started it.  The file is still on my HD, looks like about 90% complete, but qBittorrent doesn't register it.  I've tried Force Recheck, no effect.  What might have happened here?

Never mind, I restarted the system and the situation is back to normal, 87.2% downloaded

Alright. Closing the thread, but remember: Report the bug if you can reproduce it.
