Bugs

A couple bugs noticed so far.  (Update: 02/16 - Hotfixed)
    - Game crashes when opening certain teirs, seems to be different for different users.  (For me, my game will crash when trying to open Expert on both iOS and Android)
    - The cloud save prompt saying that the cloud has more data than your current game is wrong.  (I've only seen this on iOS, Android seems to be working fine)

New Cars 

   8 new cars - Sesto Elemento and 7 NASCAR vehicles.

New Tracks

   Daytona International Speedway - Motorcycle Course
     (Very tight, reminds me of the Porsche Dynamic Course)
  
   Daytona International Speedway - Speedway
     (Very high banks, not sure about the physics yet, but this could be fun - so far almost every car go full speed here without brakes..)

   Daytona International Speedway - Road Course
      ( I seem to like this one better than the Motorcycle course, a bit more speed at the end)

Questions

   Does the NASCAR way still work?
     NASCAR way still works - you can disable NASCAR vehicles  (update: might not be able to disable all cars though...)

   Does P1 GTR Ironman still work?
        - Update more info here: http://myrealracing.club/comment/79973#comment-79973 

        - I think this one is gone, I ran a test race, and after bot 43, there was nothing.  The bots also run different lines now, and block you from the inside pass.  Looks like from the above link, the train is still there, but much harder to catch now.
