Certainly. I had four torrents running, none of which were near finishing. I have it set to seed until it reaches a 50% ratio. I had finished probably three or four torrents since I set it up, all of which worked fine. When those finished I added these which had been running for days before this problem.
I power-cycled the box last night and nothing changed immediately. However, after about 30 minutes I checked again on a whim and the Download Tasks section was back. It was reading through the existing torrents and I guess verifying them, 2% at a time, until it caught up and started downloading again. Very strange.
