I'm saying the first one said he fled after I killed him so it glitches but I THINK I can grab the second now. I couldn't before for hours and hours.
When I get home in an hour it'll be the first thing I check. I said check again at sequence 7 because that's where I am.
I'm only saying this because I think I seen the skull again on my second screen app.
As for clearing the white areas I was talking to the other poster who can't find the last mission.
When you do everything in an area.. Known by holding L2 it'll turn the area yellow on the map. I was telling him to check for any spots that aren't yellow yet to find the last mission if he's been clearing the areas as he comes to them like I do. --- "Nothing is true.Everything is permitted."
