u/Biggy-Raccoon

I made my save right when the game came out and spilled hours upon hours into it. I took a break a couple of months ago and I havent tried the cartel update until today. I was never sent a text by the Benzies to meet up in the black van outside the motel, I think because I already unlocked all the ares except uptown. I did some research and found out I needed to just spray paint things, so I did and I unlocked the new area, but I never got access to "finishing the job". I even put in a command that I found and I got the achievement for beating them? idk this is super confusing. I want to do the mission and get the bomb and blow up the house and then buy the manor but idk how to get it working. as of now, theres no benzies but I also cant buy the mansion so... I really hope I dont have to make a whole new save, do i?
