Guys has anyone checked the Mural and the walls around it while the Chiliad UFO is in view
Yes, I have checked while it's there and nothing is different.
I emailed R* because I was one of the unlucky ones who managed to skip a mission (68/69 completed after the final mission). After a few back and fourths about the possibility of getting the save file fixed, I asked if they could give me a clue regarding all of this as compensation for the 65 hours of play I lost.

Thank you for contacting R* Games Support and for your question.
Although there is no information to release on this topic, we appreciate the fact that you are interested in our games and recommend staying tuned to @RockstarGames on Twitter and http://www.rockstargames.com/newswire.
Not sure if that's a hint that they will eventually tell us or not, but I'm cautiously optimistic.
P.S. I've done the Chilliad UFO using a save file I bought on ebay.
