Regardless if it’s an obvious bug or not providing more info helps. It’s happened to me too especially annoying since it was in Hungary where I got myself a good higher downforce set up only to be forced into something that’s more suitable for Monza I didn’t notice before parc ferme and that was the race ruined. I always double check now to make sure it doesn’t happen again.
Also in career mode and it happened to me way before the latest patch so it’s not that. Could this potentially be moved into the technical forum @Hoo?
