Making me redownload the entirety of ffxiv after power outage

[Klayrewolf]

So yea, this is happening to me as well as a few others, I've noticed there hasn't been any replies for a fix from anyone (SE included) on the previous thread so I figured I'd start a new one explaining the happenings.
So I was watching a cutscene in one of the new areas when my power went out. This has happened to me many times before in the past yet this time was the only time it asked me to redownload a patch and not just the stormblood one, but the entirety of the game. Now on top of dealing with the other problems this games launch has encountered, there's this.
I'm in the middle of redownloading the 22gb update, which will take about 5 more out of 10 total hours but I've heard that the people this has happened to, keep encountering the same issue and I'm wondering who else has this problem, is there a fix, and what other information people/square can about this
Edit: I should probably add that this has happened to me on ps4
