Peacekeeper achievement bugged (not working)

[Varathius 11]

Hi all,

Question: When I first beat the Arma 3 campaign, I was able to save all Nato members and one of the rebels. I still only got the "every man for himself" achievement, which I thought was odd. So I replayed the final mission (game over), took a ghosthawk, saved ALL 4 rebels and all 3 Nato members (all of them) and still did not get Peacekeeper achievement.... 

Any ideas? This appears to be bugged.

Sorry guys, never mind. It was the mission before and I had to revert it and go with the Nato invasion instead of the alternative ending. All solved. !
