I observed a very high uT CPU usage during file hash check (full core out of two). What was strange, was that in a 17GB torrent with 3 (in middle of all) files present on disk (not fully downloaded) and other 47 skipped, it managed to swiftly reach the beginning of these three (~24%), check through them and - check further (!) with increased CPU load... Checked the files, that were nowhere to be found. (They were once present, but then deleted.) After accomplishing the task, uT did not start the download process itself, even though it was set to it at the beginning. After manually stop-starting, the speed increased as it should and after like 5 seconds uT froze... Hash dump of that freeze: DUMP There were many such freezes.
