Hi all, I have the same problem but in my case I am using the Yugo cars and Corsa VRX mods, but it happens just when I race in rain, it doesn't matter how % of rain or multipler for fuel and tires, Ai pits in the first lap and, actually, they don't stop, they pit every lap just for, I guess, "change tires". I tested with vanilla cars, I am not using aniversary patch, and I tested this with vanilla tracks also like Enna, Anderstop South, but the same happens. By the way, I tried to fix this by changing the tyre types of the mods to vanilla micheline tyres, and this seems to work at first because Ai now doesn't go to the pits on the first lap, but when they go into the pits to refuel, the problems start again, on the next lap they will go into the pits to change tyres.
