Alright well found a piece of barrier along the inside wall of the banked turn witch is invisible when you drive by it but partially visible from the oposite direction, noticed it when i lost control coming out of the bank and slid along the wall and magically got propelled into space here is a screenshot

Yeah, thats where a barrier would be if you were driving on Kyoto GP. It sorta seems like didn't get rid of all of it when making KY Oval/national

well I hate this little bug... when you hit the infield wall after T1, you normally do not flip. Once I spun in the banking and went into the infield wall. everything happened as normal, but then I got flipped all of the suddan. I didn't even realise what has happened. When you come from the anti-clockwise direction, you just see a white pixel a bit away from the usual wall, wich flips you
