First of all, good work but...
Scawen... you noticed this?
Where are braking panels in aston?
(see the attachment)
Also in KY there are some "holes" in the walls of the oval for example. Shortcuts bumps are missing in the exit of KY1 to KY3 (in the chikane)
A wall in FE is missing into the railroad.
Ramps, if you get down of them slowly from the high side of the ramp, it do a "catapult" or "cannon" effect and bump you with a high speed like the old red barriers walls.
Thanks again for the test patch, i hope my review be usefull
