Missing skidmarks and dirt plumes

Hi there..

Stunning game, love it - one small thing though, I'm running version 3.0.1 (think thats it anyway, the latest update anyway with the car colour changes and the Bollide now more drivable) and I suddenly seem to be missing skid marks and particle effects from dust etc when offroad. I don't mean I'm getting the orange placeholder texture for skidmarks etc, I mean they're missing entirely.

I only noticed when I got the Grand Marshall stuck in one of my favourite crash spots on the industrial map - normally it throws up big plumes of dirt and lays rubber down the road when I charge off, but as of the update, nothing at all. Weird. Anyone got any thoughts? I could try a re-install I suppose.

Also, apropos of nothing, I notice you have dynamic shadows when the headlights are on - top work those guys, thats one of my favourite effects

Thanks.
