Race: 35 mins(~18-19 laps) with 24 AI's Tire Wear=normal , Fuel Usage=x3 (8-9 laps/full tank) All AI's, one by one on lap 9 just drove to the side, stayed there and auto back to garage(end race) when they ran out of fuel. I was wondering what was going on so I pitted to refuel and found out that I wasn't able to. On the dynhud you can still adjust how much fuel you need. The AI's did not even pit for any damage(pile up on 2nd lap). Was this changed to this car like the other ones where you can't refuel or an issue? Edit: Sorry if this was in wrong place.
In one of the latest patchs most series were updated to reflect real life refuelling rules. I believe they are working on UI solution for a future patch so this is more visible. In order to allow refuelling you'll need to start your race from the "all cars" icon.
