I saw some old post about people having similar issues, but not sure I ever saw a fix Ran a 20lap race (Brazilian stockcars at Montreal) with manual pit stop and refuelling allowed. Came in on lap 11 and car was filled up with fuel, but it held me there indefinitely. All the AI came in, refueled and continued on. After a couple of minutes I had to exit the game as it wouldn't let me continue.
