Just on the conspiracy theory... I have had my ps4 since Christmas and encountered my very first error literally when 4.05 was released. When I say literally.... I got the error, restarted game and got the error, checked for system updates and 4.05 was there. I checked and it had just been released...within the last 5 minutes. My PS4 had had no changes for the week prior and worked perfect.
Coincidence.... or occam's razor
