Also, a great bug -
steal a tank and go max wanted... drive that tank into Vice Port from the north, past the Pay-N-Spray, and a cop car flies off the roof at you. (It's supposed to spawn on the street)
That's not a bug, it's just how R* scripted the Police car up there, it's funny, I know
And probably most of you know that, you can visit the bank you robbed in "The Job" after that mission, and get some money, but with 4 wanted stars.
Also, the sky mod looks nice, I'll try it one day.
