I have just noticed a small bug, as i have been doing quite a bit of racing again lately...
The AI seems to not always take the correct amount of fuel for races. I just had a race with a friend of mine and AI (mod: Pochete 118 GT3) and the AI cars that were set to difficulty 4 ran out of fuel 2 laps before the end of the race (12 lap race on Aston North, they ran out in i think lap 10). Interestingly the AI set to difficulty 5 finished the race without a problem.
