I'm trying the public-beta with new UI, and all mods have been updated. I tried the Marussia MR01 at the new Cote d'Azur track. If I drive with the default setup all is well. If I change the steering range to "10.x:1 Monaco", when I go on track, the wheels of the car suddenly cross over towards the opposite side and meet in the middle. I'm not joking, the wheels move to the middle of the car front-end, and it's impossible to drive.
This is long story, much longer than the new UI. Just chose 10x1 without "Monaco" and it would work fine.
