No bugs to report here and everything looks fantastic, however, I do think the kerb on the exit to the right-hander at he end of the back straight should be flattened.
A lot of people use that runoff to provide space to other drivers on the inside line when exiting that corner, and I've found that those new kerbs can unsettle the car a lot if you get a tyre over them.
In one particular case, I was taking the FBM around to get a feel for it, dropped the left side tyres off the edge of the kerb as normal, and as I moved gradually back onto the track, the rear tyre caught the kerb's back edge and violently flicked the car over into the middle of the track going sideways on two wheels.
It would have meant race over for anyone behind or on the inside line from me. People I would have avoided, given a preference. The track as a whole feels a lot tighter and more dangerous now, but that bit felt a little unnecessarily dangerous...
But that's my only real gripe - the rest of the new kerbs should make things interesting in a good way, I believe.
Another tiny, minor thing; a spectator camera angle on the historic course where the cars have come out of the hairpin and are heading for the new section of track - it's down on the kerb in the chicane, miles from the action and it's only there for a split second, then it switches to the next camera. Just seemed a bit out of place...
