A friend of mine who plays FFXV on PS4 just recently got a new update with the last several hours of playing this morning (2am of 3/24/17 pst)

the update file in question is:

"H2017.06.06.0000.0001f"
with a size 26145.35MB.

Now it changed to "H2017.06.06.0000.0001g"

I heard this happened to other users a lot but has there been a known fix to this issue? Like, would they have to reinstall the whole game again?

EDIt: It appears that the letter at the end of the update name is changing letters as it goes on going through the alphabet.
