Not sure where to proceed. Finished memory block 3 with every task completed, same for memory block 2. Memory block 4 still remains unlocked, and I can only play Memory block 3 from the start if I try.
Im having the exact same problem as theeconomist. I think this part of the game is bugged, because I cannot continue due to the lack of indicators on the radar. I am unable to find necessary objectives required to continue.
