I installed it a day ago and checked my profile at Rockstar Games Social Club website and my career overview page there and no ban indication's and no email's from Rockstar at my email accounts affiliated with them!..
Only thing I noticed was that there was only one duke of death on the map, and I choose the car for Trevor, I'm not sure if the spot you find the duke of death at respawn's additional copy's for the other protagonists owe and when I changed the car color to sun rise orange, when entering the players garage it reverted back to flat black, but had the custom wheel's I bought it on it!..
I seen the stun-gun, rail gun and hatchet at Ammu-Nation and the email's for the nature photography and Monkey Mosaics and additional stock car racing also showed up!..
Just remove the two collectable files from C:\Users\username\Documents\Rockstar Games\GTA V\Profiles before going online to play, I'd zip them up and put the default ones back in when you decide to go online
I don't play GTA V online yet or have any plan's to do so!..
The Duke of death maintained it's Sunrise Orange color when I saved it in Trevor's trailer garage, but the other night when I used Franklin to find the duke of death and had it sprayed Sunrise Orange, it's color wouldn't save in Franklin's grove street garage
