I didn't lose anything due to the update, but I don't see how to unlock new missions.......I beat the story mode on normal, and I beat boss mission 1 and 2 before time ran out, but nothing else unlocked.

Anyone know what brings new boss missions?

After a recent update on my PS4, my Raiden V game lost access to all boss missions, leaving only the first one available. How can I unlock all the boss missions again?
