Snow or black grass at both Daytona and Laguna Seca tracks in hot weather

Has anyone else witnessed snow or black grass on the side of the new tracks mentioned above?
It doesn't seem to effect the car's handling and in this case I was using GTE cars. Just a glitch, I know, but also floating cars and spectators on the side of the track as well.

 

I think what you are witnessing is the foliage bug. I get it if you set current date with real weather for the future (25 min race with 60x time acceleration (24 hour cycle)). The system doesn't know what season and weather to display.

 

Yeah, setting real weather, but normal time. Probably just a bug with new tracks.

 

had the very same happening at imola on a custom championship. the track also had all the side objects removed, it looked like a phantom track.

 

What date was set, to reproduce it?
