I have black ops 2 on PS3.
I had not played for 2 months, and when i came back, i have downloaded and install a very big patch, NO PROBLEMS.
Then I have purchased the Season Pass, and downloaded it NO PROBLEMS. All old maps worked.
Then I have downloaded UPRISING first, and install it, NO PROBLEMS. All old maps worked.
Finally I have dowloaded REVOLUTION and install it. PROBLEMS, half of the old maps does not work (the status line at the bottom stop after 1/2 sec and nothing else, I have to switch off the PS3 to solve it. It does not work on HIJACKED - EXPRESS - MELTDOWN, and it works fine on RAID and some others ...
