I am constantly seeing files that are in seeding (I assume that this means that they are %100 downloaded) but when I do a force recheck they still need to download a few %. I first found this when a movie I thought was finished only played to 68% and died. I went back to deluge and did a force recheck on the seeding torrent and it still had %30 to go

Deluge needs a force recheck on completing option or to fix this bug!
I highly recommend that you do a manual force recheck on all completed downloads, and a second one if the first showed that you still need some data.
Anybody else seeing this issue?
I'm running 1.1.5 on Kubuntu 9.04
