159 wanted posters. When I saw this achievement I said "Fuck that!", but two weeks later I caved and decided to do it. It wasn't fun, but it's done. 
 
Or at least I thought it was done. After the fucking hours it took me to drive around and collect every goddamn poster, the game glitches on me somehow and says that I have 158/159 posters. I thought to myself "Oh, I must have missed one somehow", so I went to view what I was missing.
 
Poster #106 apparently. I look it up online, see the spot and I noticed that it looked familiar. Sure enough it was familiar because I had already gotten the motherfucking poster and it isn't counting it. 
 
I want my S Rank...help me.
