When I look back at old replays I see my current selected car in the replay. I tried this with different replays and different selected cars. The example below has an IR18 what should have been a BTCC car.
This is normal when you no longer have the car that was originally used. Presumably this includes older versions of the same car.
I uploaded a differerent replay due to file size.... I had a closer look and I see all replays after 21-2-2023 are ok and the once before are showing these replacement cars. I think something changed during the latest Q1 update
Maybe a side step regarding replays. It would be great that the replay section also gets these checkboxes so we can delete more of them at once via selection instead of one by one...
