Im also having this issue, though i've been downloading this time for about 2 hours so far. I had a download going for like 2 before it, but it crashed and I had to start it over. Really nervous about leaving it on over night because of the earlier crash. I had, quite literally, a one second power outage in here that shut off the PS4. Its really a bummer since i had been looking so forward to playing today after working every day since last Saturday.
