I've been running single player races lately and some categories have a weird glitch. The vehicle gets stuck on the track geometry and the tires get spiky polygon syndrome. The vehicle is then unable to move. Tyre values are glitched when this happens, and damage is indicated even with damage deactivated. This notably happens in the TSI cup. It doesn't seem to be track related either, as I ran different categories in said tracks without problems. Someone else on Steam has this issue too with other categories. I made a clip showing it happen live at Adelaide. Screenshots are below.
