Have you tried adding any of the Late Night buildings to Riverview? I only have the Sports Grill one in Sunset Valley and just the 1 station is all I needed to make the tips. Could see if you can fit one of the buildings with the built in subway and see if it works?
D'oh. I hadn't even thought of that. I guess I thought it might mess up my game, but if I save a backup file it shouldn't be a problem. Good idea. I will give it a try.
What I *did* do was reset the sim by sending him on vacation and then I had him work the exploit for a bit longer. He's not raking it in because I'm just not that patient, but when he came back he was getting tips again. Part of the problem is that he's a 2 star celebrity and the paparazzi are taking over, just snapping pictures and everybody else has celebrity interactions instead of tipping him. Everybody else just grabs a book and reads whenever he's playing lol
