Pretty sure this is not a bug, as just yesterday I remember highlighting ghosts on the ps4 dashboard, hitting the option button, and going down to the "information" tab clicking on it. Which it showed the patch/version number as 1.06, after today's patch its version 1.07. I will say it is odd that the patch file size is the same each time recently though.
I have the update also, my problem is that it never updates. And so I can not play Ghosts what so every now because of it.
