Tracks Fast Lane AI not appearing anywhere, custom track

[Roosteer]

As said in the title, I made a track in Blender, link to all the AC files here:

118.35 MB folder on MEGA

10 files and 5 subfolders

mega.nz

I fixed the surfaces and everything, but every time I record a fast lane lap, it doesn't produce the candidate file, I click Save AI, and when I hit exit, the game freezes and I have to shut it down manually. Any help with fixing this?

Thanks a million

When you exit it does the processing, can take a few minutes if the track is long enough.
