So i just had a look and my external harddrive is nearly full (about 20gb off) maybe thats messed with it? I have the optional to move the game directly to system storage, or should I uninstall and reinstall on the PS4 itself? Sorry for the barrage of questions, i’m useless with this stuff!
I haven’t done it before, but from googling, my understanding is that using ‘move to system storage’ will move the game onto your PS4’s internal hard drive.
