I was playing gta 4 the other day trying to get the endangered species achievment (kill all 200 pigeons). I had 197 (or three left to kill) of them killed, it was starting to get late so I saved the game then went to bed. Next day I wanted to finish the achievment so I went to stats and it said 137 pigeons killed.....WHAT THE HELL!!! I tried to load the prievious game but it still said 137 pigeons killed, has this happened to anybody else because I'm going to complain to rockstar about this.
