to assist other baffled parties if you already progressed through all quests (and did Olga orb stuff ages ago...)The updated content begin by going to speak with Koba in the rebel base after getting the prototype for Olga.
(1) Find Koba (as in remember who he is not having played this section in ages)
(a) Sanctuary,
(b) go to inner sewer (where the prison crew idiots are) and
(c) turn Left instead of entering prison crew idiots building
(d) turn Left again to talk to the chap and enter to talk to Koba and Vice
(2) Koba and Vice are there: long conversation to get to go to talk to Razin to get new prison mission again.
