I did not see it mention before here (I could have missed though), but I just came across a funny little bug in the NASCAR series. In two separate hunter races on Dubai Oval (I did not check other hunters so far, so unknown if it is just this specific race).

I noticed first some extreme, impossible distances to overcome and could not run into first place, but coincidentally I found out the cause. When you finish this hunter race and hit retry from the result screen, it counts back only from 5 seconds -as is common with a 'retry race'- but with the car to chase also leaving at 5, instead of the 10 seconds of your usual delay here. So instead of winning back those 10 seconds, you gain already 5 at the start, making the winning distance from 5 additional seconds longer. Easy win now!

I don't know if this bug already existed as I usually need only one try at hunters, but it just came up now.
