I've got something weird happening here. I can get to the line with all the other cars , and as soon as we are all supposed to leave the starting grid.....the AI all seem to disappear. Either they retire from the race or they all just automatically go back to their pit area and don't move. This is every DL track so far. Such as Watkins Glen , Blackwood , Laguna Seca , Mid Ohio and a few others? I have a feeling that it's maybe something I'm doing wrong. But with everything set exactly the same , the races run perfect on the stock tracks that came with he game. Anyone else have an issue like this?
