It crashes my game just after the track loading screen. I noticed that with a few mods that i have installed so i've left them out of my game.
Yeah, never realised there was another Boss mod kicking around. Never had any trouble with the one Carlos used in the racing club. THe Cougar is a bit trickier to drive and is unfortunately too slow to compete with the Boss, which is a shame as a series featuring the two would've been great. Still, it's a good mod in its own right but i've yet to sample it in an online race...
