I have experienced these time glitches, not on W5 yet. On world 4 twice I have had 8 hours tagged onto a job. Did everything, delete jobs, start again, shut down computer, cleaned cookies (clean oven just to waste time). First time it was the last job of the night, I still submitted a ticket by morning all was well. Second time it started in the morning. I submitted a ticket that time also, but I just had to wait it out. I have read other threads about this issue. I would say to send in the ticket just so the dev know how often this is happening.
