Texture or landscape problem

[FlutterShein]

I have a pretty big problem, I don’t understand how it started or when, I used to be able to go down in the subway, but now when I try to do it a weird thing happens, I fly right through that spot and die from falling, but I don’t fall, and if you spawn a car in that spot it starts endlessly teleporting from top to bottom until it breaks. How to fix this?

Also if there is a marker under the ground, I try to teleport to it but I get pushed to the surface, where did I make a mistake?

Its a problem with the wireframe
I’m not very skilled with this but this happened to me once

Don’t remember how I fixed it though

You are likely using a Config.json from another map that has Use_Underground_Whitelist set to true. Either set that to false in the Config.json of the map or add an Underground Whitelist Volume to the underground area.

Thanks, the method of adding dungeons to the whitelist helped me.
