okay, good to know on the every 5 races thing, I'll test going to Spain thenIt does exist. That would be because it does not happen every Q2. For me it's every 5 races, therefore SPAIN - BRITAIN - SINGAPORE - BRAZIL in S2 of my modded career. I have Ferrari on the Force India chassis, Renault on the Williams chassis. It happens to be both of these cars that crashes the game (I swapped for original ERP for one at a time.)
I'd also like details from others who have experienced this issue to understand whether what I have explained is the same or at least similar to their explanation. Thanks.
