I realise nobody's posted here in well over a year but it's worth a shot. I just started playing this because I found it in my brothers rooms and I was bored. I got to the the mission where theres been some guy in your 'pad' and you have to chase him. So I run and get in the car and turn around, by which time it says I've lost him. No matter what I do, everytime I'm just about to actually start after him it just says hes gone.

WHY??
