Yea no sh*t right! I mean, with the limited missions that are available to play we would be replaying the missions a f*ck LOAD anyway.
Replaying a mission isn't a glitch or exploit... Let's get that out of the way here.
I think the true sh*t here is Rockstars failure to launch online Heists in a timely manner, because the current crop of missions is not what I thought we were getting, so the only entertaining thing left to do at this point in time is level up and buy sh*t.
So you've played all 128 missions?
