GassyHaggis Sorry I forgot to come back and update my findings with the alleged PIR bug. I checked it all out again the next day and I agree it’s just an illustration bug and the car does keep its upgrades.
What I have found though, which is what I think made me think it was a PIR/upgrade issue, is that one of the AIs is incredibly fast, and far beyond any of the other AI at that difficulty level (even in the same car). It is unrealistically fast in a straight line and goes round corners on rails. That particular AI is also seemingly immune from the physics system the rest of the grid is bound by. This AI was in a race I had to win (one of the goals) so I tried to take him out but it was like hitting a brick wall and he carried on unaffected.
There’s a few other bugs around I hour they get round to fixing. My car randomly changed colours from race to race. Sometimes I get the paint I chose when I bought the car and other times it’s red or pink or blue or… you get the point.
GassyHaggis @BritishBean have you found a car to get the fastest times in the challenges for D Class in the Road D Majors tab? (Silver Surfer, NZ Club and The 200 Triple)
I’ll take a look later tonight how I’ve copied at those ones. For D Class I upgraded the GT86 from E Class, I’ve struggled in some hot laps though so will check if I managed to tick them off with the car.
