"Grand Finale" mission problem

[R@S]

Just make sure you move Tanya to the transmission area and fight off the Palinero attacks, once that is done the game is practically over. If Tanya has completed the transmission and left, you should leave as well and the game willl end. The message you get after 3 days is a remnant from something else, I think it has to do with you giving her the tapes. Since the game should be over by then you can ignore it.

Are you playing with any mods, knowing that would be helpful.
