I started playing the game again after a few years to get some of the achievements I missed, and after doing all of the activities, as the title states, my Racket Lord achievement won't unlock.
I've searched through previous threads and the most common errors seem to be cheats or Snatch locations; I have not used any cheats in the game ever, and I know there are four Snatch locations. I actually have every achievement unlocked for all the activities, just no Racket Lord. I've unlocked achievements after finishing all activities as well, so I don't know what's wrong. They're timestamped on my gamertag ("sassybill1540") if that helps for proof.
The last activity I completed was "Mayhem," and it didn't unlock. I checked the activities tab and saw that "Tagging" was listed under them, so I went ahead and did all of those just to be safe. Still nothing. On my statistics section it shows "Number of Activities Completed: 28 of 29" (The last would be "Loan Shark" and I have no money owed). I even tried to redo some activities just in case, but nothing.
Does anyone know what's causing this, or is there a quick fix? I really don't want to start a new game to unlock this when I've already done everything once already. If more information is needed to fix this I'll be more than happy to provide it.
