My problem is, the other day I was playing RDR and I got the achievement for completing all of the cooperative missions [outlaws to the end] when really I didn't, I went through the missions and when I really completed them all I got the challenge completed, how did I get the achievement when I didn't complete it? Also, I got the achievement for completing all of the gang hideouts in a single game [no DLCs or anything until recently] my friend and I where jumping around from game to game so how did I get it when I was going from game to game? Does it carry over to the free roam you go into. you get it by doing all of the hideouts is a single game.
I hope you guys can help me out ASAP,
