guys.... i think there's a problem with version 2.2 online... for me, it's way too dark... the track and kerbs and what not are barely distinguishable from black... offline it's fine... i tested on my local dedi... 2.1 is fine, 2.2 same problem... we might need/want to consider reverting to 2.1 for this event - check it out and see if you get the same....
in other news, not sure i can do this event, i honestly can't even string a lap together in these cars.... it's oversteer city and waaaaaaaay beyond my meagre talents... will confim tomorrow....
Seems fine for me, but that was offline - so it may be that there is a issue with it online.
What happens if you set the server to like 10AM?
Also, for the sliding issue, try lowing the springs by 1 click on each, putting the rear ride height up to 7 and upping the rear wing to max.
