Welp. Here we go again.
I guess I don't know how to patch properly. I thought I got rid of any obvious shortcut in ASE v2, but the same guy who got a 1:12 record in ASE v1 managed to just get off the high-surface on the path to the "Need for Speed" route and speed their way towards the ground-level shortcut to get approximately a 1:22 record.
I patched this shortcut (got rid of the lowest-height finish-line), so hopefully there should be nothing fishy this time. Massive thanks to that guy for helping my dumb self find the obvious shortcut.
With that, here's the code to ASE v3: https://github.com/K-4410/Polytrack-Tracks/blob/main/Amethyst%20Skyscraper%20-%20Easy%20(v3)
Happy racing, everyone!
