Hey...im at a point where I have no challenges to do...and I've only done around less than 50% of the game, every challenge on the map is done!. The ones I havent completed fully are the TOP MODEL and HITCHIKER challenges...and there are none appearing on my map A.T.M. I hope it's not beacause I have to do them 'perfect'ly. However I've had a slight suspicion that I have to own three properties, and I own two. Can you guys help me?
