Well everything went as predicted. Welcome to real live racing.
Multi car incident ==> full course yellow. BTW: not just a wing. A single car crash would be a local yellow.
And i think some people were lucky to not have a S/G immediately. Because the yellow flag was out and they were still racing and overtaking. The server needed to calculate everybody's position upon the incident. So it needed a couple of laps to get everything back in order. It flipped a bit at some points to get everything back in to order.
So my opinion: it wasn't a server or rF2 bug or whatever, but a people bug...
And about the contact penalty's. Don't make contact.
and some "paint swapping" is allowed.
Just as Freddy wrote: Some where a bit surprised by the sudden spawning on the grid. It's the only "bug" a found at the moment.
Reconnaissance time was to short. 60 sec + 1m30sec was just to short. It"s not often used. But I think it's a nice alternative to a formation lap. And going to the grid in real life can be a bit hectic too.
I loved qually time in split groups. The only thing missing, was a list where you ended up. But it isn't an issue for me.
I got from the back to P6 and i spinned out 3 times so it could be better.
