This has happened the last two times I have tried to do this Propaganda Broadcast in the Battery Park Borough. Kill the enemies defending the machine, press the imaginary button and then kill the two waves that come to reclaim the PA system. No key drops. I have verified my files, etc.
My screenshots are to large and cell pics won't work either. Perhaps an employee will contact me and I can upload some pictures with an attachment or something.
