I just loaded assetto Corsa again to have a look at something on the Adelaide track and my Ai was completely different, hitting every single wall! Only thing i did was copy the Ai, Data and extension folder to desktop so that i could make the winrar file.
Anyway, i just loaded the track up again in practice mode holding shift down so that it would bake the files into the track.
Loaded full race with V8 cars and all good. So just to make you aware if something goes wrong with ai.
Crazy ))))
Thanks Richard
