Gears 3 Socialite Unobtainable?

When I played gears 3 on my other account I didn’t get 29/30 war supporter that’s the achievement I need for socialite and I’m not sure if it’s discontinued or not but I heard it has something to do with coalition removing the title updates from gears 3 if that’s the case I can’t get socialite and seriously 3.0 is unobtainable I hope coalition can fix this gears 3 is one of the best gears of war games to this day.
