I've had this game for a few weeks and the game has been patched twice since I've owned it. This has happened with both patches.
When I'm done playing for the night, I put my PS4 in rest mode while ESO is still running. If there's a patch out, it will wake up the PS4 during the night/day and start the update process while the game is still running. The patch will fail in the notifications bar during this time. If I choose retry, it will say "Preparing" and get to around 23%, then it retries 4 times before giving me another failed message.
I've tried restarting the PS4, rebuilding the database, etc. The only thing I can do is uninstall the game, reinstall it, and download the 16+ GB patch.
Has anyone had this issue? It's driving me insane. Instead of playing ESO, i'm reinstalling it for many hours.
