As you can see, i finished in that place, I don't know why, but i saw this happened to other players before, maybe that happened to Axel too
Same as Ka$ha's map, is a bug of the map, because this is not the first time that appear a top like tht in the whole history of trials, maybe the map got bugged and he finished at jetmax part.
Not sure about other tops.
