Okay i've figured out the problem, there's a Lag where the Task may have actually completed an hour and a half - 3 hours ago but we still see it going as if it's not completed yet, so you may want to hit Update once an hour on your Projects it's why one of my Tasks seemingly disappeared once i restarted the BOINC Manager but really it was just done lol, i just hit update on the one that was nearly complete and it apparently finished 1 hour and 10 mins ago. The clock starts being pushed back a little when it's actually complete, so there's a lag between our Manager and the Server.
