Strange one this, not sure what the problem is. I upgraded to 6 yesterday and threw my first big batch of new downloads into it this evening. The first couple of downloads were showing every file missing a few KB but I found I could right-click -> Assemble Incompletes adn they repaired OK. They were old files (then again, 700 days isn't really "old" on Giga these days) so I thought maybe that was why but now newer posts are also doing the same thing. Any ideas? Here are 2 screenshots of my current download queue so you get the idea:

I have never seen this behaviour in v5.x so seems too much of a coincidence that it suddenly happens when going up to 6 no?
