Disqualified from race for unexplained tyre violation

Every I go to Imola, I'm disqualified.

I've been disqualified at least 5 times, in different races, two times at Imola, one time at Miami, one time at France and one time at Austria. This happened in a two player career mode, since the last update. I tried to star a fresh career with my friend, but this keep occuring.

Please, fix this thing, we paid for that, the minimum that you need to do, is fix this thing.
