Long Beach is missing some large green flags/signage that is visible as you go into turn 1 at the end of Shoreline, which is on the side of the track right around the 400 ft braking sign. This is also visible from the other side of the track entering into what I think is called turn 5. Both of these act as better brake markers, since they are large and high up.
The track also has some stutters going into that turn 5 area.
And, to be nitpicky, Will Power does not follow his preferred line into turn 5, which is to go out into the little area where the wall ends on the right, so he can arc better into that turn!
The AI seem a little slow out of the hairpin, at least in the IR18, I can pull a good 8-10 car lengths out of there, though they still beat my laptimes, these seem better than say IMS Road where AI is way too fast.
Other than this, LB seems good. The other content and code changes also seems to be working. Now, as it updates from say version 3.53 to version 3.55, it is deleting the 3.52/3.53 folders and their content, on GT3s. It has however still left the old 1.87 and 3.51 folders. I went ahead and manually deleted those for one car, and it doesn't seem to have broken anything.
