Incomplete files rename bug

[Mikado]

UT 1.7.2, with "Append .!ut" option on.

I was dloading a torrent with lot of files (and one folder, lets call it "folder1"). It went really slow, almost dead. I've stopped this task for a while.

Then, i've found another torrent with complete "folder1" (and same files in in, file sizes do match), dloaded torrent file, forced check, and uT correctly determined that it's nearly complete. Missing pieces were dloaded. But completed files (really completed, i've checked them) weren't renamed back, so previous task still shows these files as incomplete with missing pieces after re-check.
