Hello, those of superior intellect.
I come to you, a very broken and desperate man.
A few days ago, I wanted to port a track from Mario Kart 64 to easily learn how to make drivelines, checklines, etc.

Every single time I try to render the track, it gives me one more error, about a random vertice. The vertice is part of a quad. There are no broken quads touching or even near the vertice. I have even completely deleted and remake the segment several times, hoping it would fix the issue but it still places the error in the same exact spot.
Even more confusing, when I delete the antennas for the track, the error goes away. (At the expense of making the track unplayable).

I have included the blend file. Anyone, who is knowledgeable over blender, please tell me what I'm doing wrong. I am so exhausted.
I am using Blender 3.1 if it matters. Thank you.

The blend file:

your drive graph is full of bad quad vertices

Oh god, I didn't even notice that. That explains a lot.
Like I said this is not only my very first time trying to make a track, but also one of my first times even using blender.
Thank you very much.

Doing better than me on the first time haha

@Benau I didn't realize Blender 3.x was supported, but I guess it makes sense.
